PACS Commissioning phase,Pointing Verification
andPerformance Verification PhasePlanning
Review(PVPhot)

• Koryo Okumura / Marc Sauvage
• CEA/DSM/IRFU/SAp

2
Cooler Recycling 1 (CPPhotCooler and PVPhotCooler)

• Same as the commissioning phase

3
Photometer orbit prologue (CPPhotSetup and
PVPhotSetup)

• Same as the commissioning phase except for the
  bias table which should may be updated after the
  commissioning phase
• Bolometer bias setting
• default table is BOLObias_ILT_standard_low
• Internal calibration source (CSs) is switched on
  and set
• default values of CS148 and CS258 Ohm
• Wait for the stabilisation of the CSs
• default 2100 sconds 35 minutes
• Total duration 2272s 38 minutes

4
PacsEng_setCSsTemp (PVPhotSetup)

• For some execution of the prologue the CSs are
  set to very low levels
• At some stage CSs should be set using this CUS
  script
• The stabilization time is set to 2100 by default
  from 4 to 48, 58 Ohm
• The stabilization time from 48, 58 to 80, 92 Ohm
  is shorter and set to 1800 seconds 30 minutes

5
Photometer orbit epilogue (CPPhotSetup and
PVPhotSetup)

• Same as the commissioning phase

6
OBCP_chopped_photometry (PVPhotBol)

• As in the commissioning phase we can foresee some
  small calibration blocks
• Currently this is not yet in PVPhotBol

7
VRL and VH_BLIND exploration (CPPhotBol and
PVPhotBol)

• Same as the commissioning phase, but shorter
  because of a restricted parameter space
• VRL 2.4, 2.1, 1.8 V
• VH_BLIND 0.05, 0.1, 0.2, 0.4, 0.6, 0.7, 0.8 V
