PHT Instrument Page

We recommend the ISO Handbook, Volume IV: PHT--The Imaging Photo-Polarimeter as a general reference point. Latest updates and further details on calibration can also be found in technical notes and publications available below.

  Calibration

  Different aspects of the ISOPHOT calibration, which may be of relevance to future space missions are addressed in detail in the following papers:
  • "The Pre-Flight Calibration of the ISOPHOT Instrument" - D. Lemke & J. Wolf
  • "ISOPHOT In-flight Calibration Strategies" - U. Klaas et al.
  • "ISOPHOT Point Source Calibration - Wrapping it Up" - B. Schulz
  • "Analysis of ISOPHOT Chopped Observations" - P. Ábrahám et al.
  • "In-orbit Calibration of ISOPHOT-S" - J. Acosta-Pulido & P. Ábrahám
  • "Absolute Surface Brightness Photometry with ISOPHOT" - Ph. Héraudeau et al.
  • "Straylight in ISOPHOT?" - D. Lemke et al.
  • "Photometric Mapping with ISOPHOT using the "P32" Astronomical Observation Template" - R.Tuffs & C. Gabriel

  Additional PHT Documents

  These additional PHT documents describe aspects of the instrument in some detail and only need to be read for a deep understanding of a particular aspect. But be aware that the reports sometimes reflect "work in progress" and may have been superseded.

  See also the proceedings of several ISO Conferences and Meetings for specific instrument related topics.
