J/AJ/135/2245  Absolute spectrum of the Sun and Vega for 0.2-30um (Rieke+, 2008)

ADC_Keywords: Sun ; Spectra, infrared ; Stars, standard Keywords: stars: fundamental parameters - Sun: infrared - techniques: photometric Abstract: We determine an absolute calibration for the Multiband Imaging Photometer for Spitzer 24um band and recommend adjustments to the published calibrations for Two Micron All Sky Survey (2MASS), Infrared Array Camera (IRAC), and IRAS photometry to put them on the same scale. We show that consistent results are obtained by basing the calibration on either an average A0V star spectral energy distribution (SED), or by using the absolutely calibrated SED of the Sun in comparison with solar-type stellar photometry (the solar analog method).
