Data Set Overview
=================
The IKS data from Vega-1 came in various forms.
The initial submission from IKI by Dyachkov was in
GROUP FITS (binary) for the 'imaging channel'. A
separate submission came through the IHW Infrared
Studies Discipline and also contained data
presented in the FITS format (IHW keywords) for the
two 'infrared channels'. In the former case, the
three Pvalues carried information on the distance
and two angles used to locate the position of the
comet on the slit. The other simple keyword values
marked only the date, mission, and experiment. The
latter data, had not only 101 individual spectra
for the 3-5 micron measurements but a composite
'final' 6-12 micron spectrum with associated
'figure 7' from the published results (COMBES, M.
et al. 1988, Icarus, 76, 404). For these 101
spectra a cometo-centric distance was quoted rather
than a time; no time was appropriate for the 6-12
micron data. Using this information, the distance
range was 270534.9 to 39273.22 km. From this
comparison, it is inferred that the distance quoted
in the IKI submission is also cometo-centric
(31596.0 to 16092 km).

that the distance quoted in the IKI submission is also
cometo-centric (31596.0 to 16092 km).
