MIPS : Aperture Corrections |
|
Over the past few months the MIPS IT and IST, as part of a large project
to better understand and to improve the MIPS photometric calibration, have
determined different aperture corrections for the current MIPS Photometric
modes (24 um, 70 um, 70 um fine scale and 160 um) plus Spectral Energy
Distribution (SED). The present tables are a first attempt to summarize these efforts, and although we don't expect dramatic changes, they should not be taken as the last word on the subject. For our calibration purposes, where single stars or asteroids are observed using photometric observations, we use the following values:
James Muzerolle, Karl Gordon, Chad Engelbracht and John Stansberry (MIPS IT) obtained the original corrections which have been cross-checked by Dario Fadda, Nanyao Lu, William Wheaton and Stefanie Wachter (MIPS IST).
