Irradiance Calibration of Space-Based Infrared Sensors
Abstract
The purpose of this work is to develop a basis for irradiance calibration of space-based infrared sensors. It is an extension of previous work that fully defines the context of the calibration, and the concepts of spectral composites and templates. We discuss four major accomplishments during the past year and our plans for the future. The accomplishments are: 1) Data from the MSX/SPIRIT III CBO6 celestial background calibration experiments have been reduced, validated and analyzed to produce a sub-network of calibration stars that are now integrated into the current calibration network. 2) The absolute calibration of the infrared radiometry of the MSX Point Source Catalog, Version 1.2 (PSC1.2) has been validated. 3) An Air Force Bright Spectral Catalog (AFBSC) Version 1 has been developed and delivered that offers a new set of spectral (2-35micrometers) irradiance calibrators selected from the IR-brightest sources in the sky. 4) ASTCAT Version 2.0 was completed and delivered to the PL DAC in support of the MSX Point Source Catalog.
