- PACS_Phot_DPU_DMC_Setup_OBS, calling PACS_Phot_DPU_DMC_SetupBR - PACS_Phot_Switchon_OBS, calling PACS_Phot_SwitchonBR - PACS_Phot_Sequencer_Setup_OBS, calling PACS_Phot_Sequencer_SetupBR - PACS_Phot_SPU_Setup_OBS, calling PACS_Phot_SPU_SetupBR - PACS_Phot_Cold_Startinputsignal_OBS, calling PACS_Phot_Cold_Startinputsignal (Duration: 637 sec)BR - PACS_Phot_SPU_Reset_OBS, calling PACS_Phot_SPU_ResetBR - PACS_Phot_Switchoff_OBS, calling PACS_Phot_SwitchoffBR
4. Instrument switch-on and connection of the warm electronic boxes
- currently done with tcl-script PACS_Switch_On.tcl (maintained by FGB)BR - after execution: PACS is in SAFE mode, the bolometer groups are off, but the
- temperature sensors are on
5. Cooler recycling (only at HeII temperatures)
- starting out of SAFE mode (groups off, temperature sensors on) BR - CUS script: BOLO_cool_recycle (no sub-procedures are called,
- the groups and temperature sensors are not touched, HK_list is set
to PHOT_HK and in the end reset to "NON-PRIME"), Duration: 7928 secBR
- ending up in SAFE mode (groups are off, temperature sensors on)BR
6. General Setup for Photometer Operation (at warm, HeI, HeII temperatures and after cooler recycling)
- starting out of SAFE mode (groups off, temperature sensors on)BR - CUS script:BR
block PHOT_setup calling the following CUS procedures (will be renamed to PHOT_orbit_prologue):
(*) certain parameter values depend on the temperature environment!BR
- ending up in PHOTOMETRY mode, but SPU processing has not yet startedBR - Note: filter is in position "A", chopper at position "0"BR - calibration sources are set to default values, but need 40-50 min stabilisation time!!!BR
7. Operation of the bolometers (starting out of PHOTOMETRY mode)
7.1. start/stop of bolometer data flow
CUS scripts:BR
7.2. Change of the bolometer data/sequence mode and gain
CUS scripts:BR
7.3. Take data with manual chopper & filter movements
CUS scripts:BR
7.4. Take data with pre-defined OBCPs
CUS scripts:BR
- procedure PHOT_spu_setup ---> bolometer data flow runningBR
- block OBCP_chopped_photometryBR - block OBCP_chopped_photometry_ditherBR - block OBCP_phot_freezeframeBR - block OBCP_phot_cal_IBR - block OBCP_phot_cal_IIBR - block OBCP_phot_cal_IIIBR - block OBCP_phot_staringBR - block OBCP_phot_chopper_scanBR
- block PHOT_all_aots_OBSBR
- procedure PHOT_spu_resetBR
7.5. Execute AOT observations
CUS scripts (to be finalised):BR
PHOT_AOTBR
- PacsPhotDefaultsBR - PacsPhotEstimatorOBCPnBR
Logic chooses and issues a pointing mode out of:BR
- WriteOBSIDBR - PacsPhotSlewCalBR
- PacsPhotCommandOBCP7BR
- OBCP_staring_photometryBR
- PacsPhotCommandOBCP5BR
- OBCP_chopped_photometry_ditherBR
- PHOT_aot_epilogueBR - WriteEndIDBR - PacsPhotNoiseRMSBR - PacsMessageCenterBR
8. Reset after photometer operation
- PACS is in PHOTOMETRY or any other modeBR - going into SAFE mode:BR
- after execution: PACS is in SAFE modeBR
9. Instrument switch-off
- currently done with the tcl-script PACS_Switch_Off.tcl (maintained by FGB)BR - after execution: PACS is switched offBR
10. NOTES
- there are more CUS scripts related to the SFT warm, HeI and HeII which are not mentioned here (see PACS-ME-TP-007)BR - 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 libraryBR - the AOT related CUS-scripts are still under testing
