        Logic chooses and issues a pointing mode out of:BR

        • - composite_noddingBR - repeated_raster_with_holdBR - line_scan_with_holdBR

        - WriteOBSIDBR - PacsPhotSlewCalBR

        • - PHOT_aot_prologueBR

          • - PHOT_spu_setupBR

          - PHOT_fltw_moveBR - OBCP_chopped_photometryBR

        - PacsPhotCommandOBCP7BR

        • - OBCP_staring_photometryBR

        - PacsPhotCommandOBCP5BR

        • - OBCP_chopped_photometry_ditherBR

        - PHOT_aot_epilogueBR - WriteEndIDBR - PacsPhotNoiseRMSBR - PacsMessageCenterBR

Note: the default OBCP for point-source photometry will probably be the OBCP_fixed_fixed_photo.

2.5. Reset after photometer operation

  • PACS is in PHOTOMETRY or any other mode

  • execute mode PHOT_switchoff_groups_OBS calling procedure PHOT_switchoff_groups (this will reset the biases sequentially, disable the AF 17, and switch off the groups)

  • going into SAFE mode (this will disable the AF 14 for the FPU temperature checks)
  • after execution: PACS is in SAFE mode (groups are off, temperature sensors on, AF 6 enabled to check for the communication between DMC and BOLC)

2.6. Instrument switch-off

  • currently done with the tcl-script PACS_Switch_Off.tcl (maintained by FGB) (this will disable the AF 6 for the DMC-BOLC communication check)

  • after execution: PACS is switched off

3. NOTES

  • the SFT tests are described in PACS-ME-TP-007

  • some specific photometer tests, like the thermal behaviour measurements, start directly out of SAFE mode, while most of the tests will be executed after the PHOT_setup

  • the above mentioned CUS scripts (with a few exceptions) have been tested and are available in the CUS database and from the CVS library
  • the AOT related CUS-scripts are still under testing
