This file is intended as documentation of the Field(s) Of View (FOV(s))     
for the detectors and/or slits and/or apertures comprising the instrument   
on the New Horizons (NH) spacecraft that generated the data archived in     
this data set.                                                              
                                                                              
This file is a NH Project ALICE SPICE Instrument Kernel (IK), 
current at the time of delivery of this data set.
It is only provided as a convenience to the user          
to visualize the FOVs of the instrument.  This file will not be updated     
in this PDS data set as part of any SPICE kernel updates, and should        
therefore not be used as a SPICE kernel in any scientific investigation.    
                                                                              
Specifically, the references in the IK are not relevant to the graphic      
visualization of the FOV and will not be provided with this data set or     
archived elsewhere; therefore the references should be ignored in the       
context of the intended scope of this file as described above.              
                                                                              
As a SPICE IK, this file has much more information than just the            
FOV description (e.g. references to project documentation), but in the      
context of this PDS data set only the FOV description is relevant.  For     
a more complete understanding of the geometry and timing issues of the      
New Horizons mission, the user is directed to the SPICE PDS data set        
for the mission, with a data set ID of NH-J/P/SS-SPICE-6-V1.0.

If the user wishes to do any data analysis requiring NAIF/SPICE IKs,        
they should not use this file, but rather get the most recent IK from       
the NH SPICE data set and use that.                                         
                                                                              
- This file is included in document collection for
this instrument as a convenience to the user              
because, in some of its sections, it documents the geometry of the        
ALICE instrument Field(s) Of View (FOV(s)).  Other sections of            
this IK (e.g. the references) will have limited use in that scope.

    - Even without understanding that format, the Instrument Kernel,          
      and especially its comments, are human readable.  Comments are          
      any line for which one of the following three statements is true:       
                                                                              
      1) The line is before the first data marker line in the file            
      2) The line is in a section of lines between a text marker line and     
         a data marker line with no intervening text or data marker lines     
      3) The line is in a section of lines between the last text marker and   
         the end of the file with no intervening text or data marker lines    
                                                                              
      - a data marker line has the single token '\begindata' on it with       
        all other characters on the line being whitespace

    - N.B. Because padding and a carriage return have been added to           
           each line of this file, it may or may not be functional            
           as a valid SPICE kernel.

   ``Alice is an ultraviolet imaging spectrometer that will probe the         
     atmospheric composition of Pluto. A "spectrometer" is an instrument that 
     separates light into its constituent wavelengths, like a prism, only     
     better. An "imaging spectrometer" both separates the different           
     wavelengths of light and produces an image of the target at each         
     wavelength.                                                              
                                                                              
     Alice has two modes of operation: an "airglow" mode, which allows        
     measurement of emissions from atmospheric constituents, and an           
     "occultation" mode, when either the Sun or a bright star is viewed       
     through the atmosphere producing absorption by the atmospheric           
     constituents. The Alice occultation mode will be used just after New

   ``ALICE consists of a dedicated telescope that feeds a 0.15-m Rowland      
     circle spectrograph with a spectral passband that spans the extreme and  
     far ultraviolet (EUV/FUV) wavelength region of 520-1870 angstrom. Two    
     separate input channels, the airglow and the solar occultation channels, 
     direct light to the telescope. The airglow channel has an input aperture 
     40 mm x 40 mm with a boresight parallel to the RALPH boresight. The solar
     occultation channel (SOC) has a small 0.9 mm diameter aperture located   
     on the telescope side of the ALICE housing with a boresight near         
     parallel to the NH spacecraft's High Gain Antenna. A flat relay mirror   
     at the center of the airglow channel directs the light entering the SOC  
     aperture to the primary telescope mirror. The reduced SOC aperture       
     limits the solar UV flux entering the telescope to prevent detector      
     saturation at the spectrograph focal plane during solar occultation      
     measurements. A microchannel plate (MCP) double-delay line (DDL)         
     detector with dual, solar blind, UV-sensitive photocathodes (KBr/CsI),   
     makes up the instrument's focal plane.                                   
     .

     The detector electronics receive detected event pulses from the          
     detector and provide a digital indication of the spatial and spectral    
     location of each event being processed.  The event processing            
     electronics receive individual events and process them in one of two     
     operational modes, pixel-list or histogram, based on commands from the   
     IEM [Integrated Electronics Module]. Histogram mode is used to generate  
     a two dimensional map of the pixel events with the magnitude of a        
     particular pixel location indicating the number of times that pixel has  
     been stimulated. Pixel-list mode is used to generate a time ordered      
     record of detected events. Special periodic data markers (i.e. time      
     hacks) are inserted in the list of pixels to provide a fixed time        
     reference for the events. Pixel lists are accumulated continuously in a  
     "ping-pong" memory with the data in one memory bank being transmitted to 
     the IEM over the science telemetry channel while the other memory is     
     used to continue data acquisition.  The last set of pixel list data and  
     the complete histogram data are transmitted to the IEM upon the command  
     to stop data acquisition.

ALICE Field of View Parameters                                                
----------------------------------------------------------                    
                                                                              
   The Alice instrument has two apertures, the Solar Occulation Channel (SOC),
   and the Airglow aperture. The SOC is now generally referred to as SOCC     
   (Solar OCcultation Channel) to distinguish it from the SOC (Science        
   Operations Center). Since the documents to which this kernel refers still  
   use the SOC acronym for the Solar Occultation Channel, we continue to use  
   it here as well, although SOCC is becoming the standard term [9].          
                                                                              
   Light travels through a lollipop-shaped slit described below for both the  
   SOC and airglow apertures. Although [3], Rev A, defines the SOC field of   
   view as only the 2.0 x 2.0 degree "box" portion of the lollipop-shaped     
   slit and the Airglow field of view as the 0.1 x 4.0 degree "stem" of the   
   lollipop-shaped slit, the complete lollipop shape is visible through both  
   apertures [9].                                                             
                                                                              
   The spectral resolution of airglow is degraded in the 2.0 x 2.0 degree     
   "box" portion of the slit, but data is nevertheless still available in that
   portion of the slit. The 2.0 x 2.0 degree "box" portion of the slit is     
   wider than the narrow "stem" portion to observe the sun during Solar       
   Occulation Channel operations, but it is also possible for the sun to      
   appear in the narrower "stem" portion [10]. Hence, the fields of view for  
   both apertures have been defined here to be the entire lollipop-shaped     
   slit even though they are defined differently in [3], Rev A.               
                                                                              
   The diagram below (reproduced from Figure 19 of [3], and [12]) illustrates 
   the projection of the ALICE field of view onto the sky. The ALICE entrance 
   slit design shows the 2.0 x 2.0 degree "box" portion of the lollipop-shaped
   slit and the 0.1 x 4.0 degree "stem" portion of the lollipop-shaped slit.  
   This diagram shows the actual position of the Alice slit on the spacecraft,
   using the spacecraft coordinate system. It is important to note that the   
   entire 'lollipop' shape of the Alice slit is visible through both the SOC  
   and the airglow apertures [9]. The positions of detector rows 6 and 25 are 
   shown in the diagram below [12]. Rows 1-5 and 26-32 are effectively        
   masked. The slit does not image onto those detector rows [14].

   Note that because of the 2.0 degree instrument tip to rotate the +Y axis   
   (the REX antenna boresight) to the center of the box part of the Alice slit
   when using the SOC field of view [8], the axis labeling for the airglow    
   aperture in the diagram above is slightly incorrect. The horizontal axis   
   for airglow is not exactly +Y, as it is labeled, but actually -2.0 degrees 
   rotated about spacecraft +X from spacecraft +Y. The same is true of the    
   vertical axis for airglow.

   In SOC instrument coordinates, the boresight is the +Y axis, and the       
   X and Z axes are close to the spacecraft X and Z axes, respectively [8].   
   A discussion of the SOC coordinate frame relative to the spacecraft frame  
   can be found in [5]. The boresight of the SOC field of view is in the      
   center of the 2.0 x 2.0 degree 'box' portion of the lollipop [9].          
                                                                              
   We use a polygon to describe the lollipop-shaped field of view, and will   
   determine twenty-eight boundary corner vectors defining the vertices of    
   the polygon. The SOC coordinate system, field of view center, and          
   selected vertices of the polygonal field of view are illustrated below.    
   The vertices labeled in the diagram appear to be bounded by straight       
   edges, but the SOC field of view has a slight curvature, described         
   later. The vertices not shown are equally spaced in increments of 0.5      
   degree along the instrument Z axis between those shown here.

   gives the Z coordinates of the field of vectors (in degrees) as:

   Note that the projection of the slit onto the sky is not actually          
   rectilinear, but rather is somewhat curved. This is due to optical         
   distortion (mostly coma) introduced by the primary mirror. We fit the      
   observed X offset of the middle of the slit as a function of offset in     
   the Z dimension using a 2nd degree polynomial of the form:

   where X and Z are the offsets from the instrument boresight, measured in   
   degrees. The best fit values for the polynomial coefficients are:

Airglow Channel FOV Definition                                                
                                                                              
   In airglow instrument coordinates, the boresight is the -X axis, and the   
   +Y and +Z axes in the instrument frame are close to the spacecraft +Y and  
   +Z axes, respectively [8]. A discussion of the airglow coordinate frame    
   relative to the spacecraft frame can be found in [5].                      
                                                                              
   We use a polygon to describe the lollipop-shaped field of view, and will   
   determine twenty-eight boundary corner vectors defining the vertices of    
   the polygon. The airglow coordinate system, field of view center, and      
   selected vertices of the polygonal field of view are illustrated below.    
   The vertices labeled in the diagram appear to be bounded by straight       
   edges, but the airglow field of view has a slight curvature, described     
   later. The vertices not shown are equally spaced in increments of 0.5      
   degree along the instrument Z axis between those shown here. Refer to      
   the SOC calculations for determining the boundary corner vectors in        
   the case of no curvature. Airglow boundary corner vectors will             
   terminate at the plane X = -1.

   Note that the projection of the slit onto the sky is not actually          
   rectilinear, but rather is somewhat curved. This is due to optical         
   distortion (mostly coma) introduced by the primary mirror. We fit the      
   observed Y offset of the middle of the slit as a function of offset        
   in the Z dimension using a 2nd degree polynomial of the form:
