IHW IR Spectroscopy Data

Description:

This is a compendium of Near-IR and Mid-IR Spectra/Spectrophotometry from 
12 instruments. The set is comprised of 75 “observations”, of which 23 
were never submitted (these remain FITS files), and 9 calibration files 
(one unsubmitted).

Comments:

Fluxes are often listed as “arbitrary units” (because absolute fluxes are 
often not possible), but it should probably be noted that these are most 
likely F(lambda) units (as opposed to F(nu) units). Also some are not 
W/m^2/micron but ergs/cm2/sec/micron. Both of these should be noted in the
DATA_SET_DESC.

Individual Data sets: many Knacke sets are flux ratios with “Hya 106”. 
Who? Without the identifying star, the data may be useless. (#1,2,3,
4,5,6). The flux of this star, in arbitrary units, is in the CALIBRATION 
files (#4001-4004) in this directory. Should this be mentioned in the 
LBL file? HD 29461 – Yan Fernandez = Cluster Melotte 25 and star number.

Many data sets contain no information about weather conditions. (#1,5,6,7,
13,21,22,23..

FILES 15-20, 26, 27, 29, 30, 33-36, 40-42, 46-48 65-67, 4007 ARE STILL IN 
FITS FORMAT! These were observations scheduled to be made, but were never 
submitted. Should the individual files be noted in the  Modification 
History of DATA_SET_DESC (instead of a general warning) so that no one 
looking for real data wastes their time? – REMOVE & place basic info in a 
table file.

#12,28,31,32,37,38: LBL add note that wavelength has been converted to 
microns (as was done in #7) and is no longer times E3. Or change the 
comment.

#25, 50-52 LBL add note that wavelength has been converted to microns (as 
was done in #7) and is no longer times E5. Or change the comment.

#63 LBL add note that wavelength has been converted to microns (as was 
done in #7) and is no longer times E4. Or change the comment.

Explanations of flux often not uniform. Some say the flux is in units of, 
for example, 1.0E-19 Watts/cm2/micron (#72), while others (#73) are 
described as being multiplied by 1.0E19. Should this be made more uniform?
