We describe the absolute calibration of the Multiband Imaging Photometer for Spitzer (MIPS) 160 ЮМm channel. After the on-orbit discovery of a near-IR ghost image that dominates the signal for sources hotter than about 2000 K, we adopted a strategy utilizing asteroids to transfer the absolute calibrations of the MIPS 24 and 70 ЮМm channels to the 160 ЮМm channel. ... The calibration factor we derive is 41.7 MJy sr-1 MIPS160-1 (MIPS160 being the instrumental units). ...
... The Absolute Correction will be finally applied to the corrected source TS background substracted. A coarse spectrum (50 eV bins) will be produced by evselect from the source region, over the energy range used in the constructions of the TS. This will be used with arfgen to find the effective area array for the source as a function of photon energy. arfgen will be executed twice; The fist call with the spectrum in the real position (off-axis) and with the standard default parameters. ...
