PACS Commissioning phase,Pointing Verification andPerformance Verification PhasePlanning Review(PVPhot) Koryo Okumura / Marc Sauvage CEA/DSM/IRFU/SAp
Cooler Recycling 1 (CPPhotCooler and PVPhotCooler) • Same as the commissioning phase - Koryo OKUMURA - PACS CoP, Pointing Verification and PVP Planning Review
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 - Koryo OKUMURA - PACS CoP, Pointing Verification and PVP Planning Review
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 - Koryo OKUMURA - PACS CoP, Pointing Verification and PVP Planning Review
