Absolute Calibration and Characterization of the Multiband Imaging Photometer forSpitzer. III. An Asteroid‐based Calibration of MIPS at 160 μm

We describe the absolute calibration of the Multiband Imaging Photometer forSpitzer(MIPS) 160 μm 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 calibrati...
