PIA v6.3 Checklist for Chopped Data IPAC, aew 5 August 1997, v. 2.1 (extracted from PIA manual, but not produced by the PHT team) ERD window (Do FCS first, then astronomical data) Correction Nonlinearity Selection Discard Readouts Correction Read-out Deglitching Data Save Process Meas. Fit Ramps, 1st Order Poly SRD window Correction Deglitching Correction Dark Current Subtr Data Save to PIA Internal file Process No drift handling SCP Window Process Responsivity Calculation Accept as actual response the least noisy of average or median for FCS1 *or* FCS2, save print file Data Save as PIA Internal file Now select the astronomical data measurement instead of FCS measurement and repeat earlier steps for astronomical data measurement. ERD window Correction Nonlinearity Selection Discard Readouts Correction Read-out Deglitching (if "number of readouts is too low", use "test processing" to reduce number) Data Save Process Meas. Fit Ramps, 1st Order Poly SRD window Correction Deglitching Correction Dark Current Subtr Data Save to PIA Internal file Process No drift handling SCP window (Correction Vignetting causes "divide by zero" error, so skip this step) Process Background subtraction within measurement Background Subtraction Window Choose defaults for chopper steps for source and background, namely source="c" and Background="I" by clicking "ok" Click "
", Click "Subtracted Measurement --> buffer" "quit" background subtraction window Data Load (select subtracted measurement) (You have now loaded the background-subtracted measurement into SCP window) Process Power Calibration with Actual Response SPD Window Process Extract Flux Density Assign Astronomical Coordinates Data Save PIA Internal file *or* fits file Print Flux values Now open "Astrophysical Work" buffer, choose Multifilter Photometry. The resulting flux density has been summed over all pixels and adjusted for the fraction of the PSF falling on the array. The uncertainties include both the noise in the astronomical data measurement and the uncertainty in the responsivity.
