The authors present a catalogue of 226 ISOPHOT observations of 196
objects. They were observed in PHT32 mode with the
C200 detector. This catalogue is based on small maps originally designed to measure the flux
density of a compact or a slightly extended source. This catalogue is the "default dataset"
in IDA for these observations.
The data set consists on:
The final photometric values are presented in the
form of a catalogue that can be queried from the ISO Data Archive.
AAP data structure files as produced by PIA 10.0
and the same in FITS format.
A detailed report is available
List of caveats related to the PHT 32 observing mode corrected
in this work:
CAVEATs for DETECTOR C200:
FCS calibration quality restricted (ISOPHOT HB OLP caveat 10.4)
All of the listed sources were observed after revolution 94.
Aperture photometry from surface brightness maps (ISOPHOT HB OLP caveat 10.14)
In this processing the flux was reconstructed with the help of the
detector footprint shape.
The flux extraction method adopted in this data reduction scheme is based on
a simultaneous fitting of the background level and the source flux
using the point-spread function.
General caveats applicable to all PHT observations:
Signal Transients (ISOPHOT HB chapter 4.2.3 and OLP caveat 10.7)
Data were reduced using algorithms specifically developed for the analysis of P32 observations.
The most important functionality of these procedures is the correction of the transient
response behaviour of the Ge:Ga photoconductor detectors of ISOPHOT.
Incomplete Error Propagation (ISOPHOT HB OLP caveat 10.3)
Realistic individual flux uncertainty value for each measurement was derived as the standard
deviation of flux values obtained by different detector pixels.
