Query: IRS-TR 11002: Calibration of the Acquisition Images from the Red Peak-Up
  Sub-Array   We present a calibration of the acquisition data obtained by the Red Peak-Up
(PU) sub-array on the Infrared Spectrograph on Spitzer, based on repeated
observations of three K giants. This calibration is tied directly to the most
current infrared calibration based on data from Multiband Imaging Photometer
for Spitzer. An analysis of the responsivity of the Red PU sub-array reveals no
detectable deviations from linearity in the most recent pipeline version, but
older pipeline versions show evidence suggesting possible small
non-linearities.
