CEA DSM IRFU SAp 2009-01-21/22- Koryo OKUMURA - PACS CoP, Pointing Verification and PVP Planning Review2 Cooler Recycling 1 (CPPhotCooler and PVPhotCooler) Same as the commissioning phase

CEA DSM IRFU SAp 2009-01-21/22- Koryo OKUMURA - PACS CoP, Pointing Verification and PVP Planning Review3 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 CS1=48 and CS2=58 Ohm Wait for the stabilisation of the CSs –default 2100 sconds = 35 minutes Total duration : 2272s = 38 minutes

CEA DSM IRFU SAp 2009-01-21/22- Koryo OKUMURA - PACS CoP, Pointing Verification and PVP Planning Review4 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
