The authors present a full catalogue of 605 ISOPHOT observations (1228 measurements) of 542 compact objects. They were observed in chopped mode with the C200 detectors after revolution 95. The catalogue is split into two separated catalogues. Second one contains observations which use both C100 and C200 detector arrays. They are 399 ISOPHOT observations of 353 compact objects.

The data set consists on:

• AAP data structure files as produced by PIA 10.0 and the same in FITS format.

A detailed report is available here.
 

List of caveats related to C200 chopped observations corrected in this work:

• CAVEATs for DETECTORS C100 & C200:
  • Restricted signal non-linearity correction
  
  As part of the processing scheme of the C200 chopped mode, signal linearity was tested and corrected via applying a correction factor dependent on the flux level. In addition, we determined non-linear transformations between the measured signals of different pairs of C200 pixels, and used these formulae in order to transfer all four pixels's signal into the photometric system of Pix. 3. As a last step of the processing scheme an empirical flux-dependent correction was performed which - signals and fluxes are approximately proportional - corrects to a large extent for the possible artifacts related to the restricted range of signal non-linearity correction.
   
  • Aperture correction factor for point source applied!
  
  The adopted flux extraction method - fitting the measured point source function to the observed flux distribution rather than summing up all fluxes on the array and correcting it for losses outside the array area - ensures correct background subtraction.
   
  • FCS calibration quality restricted
  
  All measurements included in the catalogue were observed after Rev. 93.
   
  • Aperture photometry from surface brightness maps
  
  For flux extraction we always use PSF-fitting (the flux was reconstructed with the help of the detector footprint shape) rather than aperture photometry.
   
  • Background Subtraction
  
  In chopped mode 1-2 background positions are always measured.
   
  • Color Correction
  
  In the HPDP catalogue we present non-colour corrected fluxes. Proper colour correction requires knowledge on the SED of the object, and is thought to be the responsibility of the user.
   

• General caveats applicable to all PHT observations:
  • Signal Transients
  
  Signal losses due to detector transients - which can be dramatic in the case of the C100 detector - are at the 10-20% level for the C200 camera. Since the signal loss depends on the flux level, our flux-dependent empirical photometric correction is expected to correct for it to a large extent.
   
  • Incomplete Error Propagation
  
  Individual error bars for each measurement are obtained as the standard deviation of flux values obtained by different detector pixels. In parallel the empirical total uncertainty for the group of measurements having independent flux prediction ('secondary standards') are also assessed by computing the standard deviation of the [measured - predicted] flux differences. The final formal uncertainties were determined by combining the two types of error bars. As usual in the case of C200 measurements the dominant factor of the measurement uncertainty is the sky confusion noise.
