DESCRIPTION    = "This file contains data from the VEGA 1 IKS experiment      
                  taken in 'imaging' mode.  In this mode the image of the     
                  comet is projected onto a moving grid.  Measured minima     
  and maxima at each point are then used to derive the dimensions of the      
  nucleus in two directions approximately parallel and perpendicular to       
  the comet's orbital plane.  For details and further references, see:        
                                                                              
  Combes, M., et al., 1986, 'Infrared sounding of comet Halley from           
     Vega 1', Nature, 321, 266-268.                                           
                                                                              
  Note that the angles (Theta and -Phi) are defined on an orbital diagram     
  provided by IKI in the cometocenter system.  In the comet-sun plane,        
  theta is the angle between the plane and a comet-spacecraft line; Phi is    
  from the comet-sun line to a projection of the spacecraft-comet line.       
  Measurements are taken in two infrared bands: 7-10 and 9-14 microns."
