Abstract
The known infrared catalog has limited available quantity, limited coverage of waveband and irradiance, low intensity distribution. This can not meet the need for astronomy calibration of existing ground-based infrared radiation measurement system. According to the system detection waveband, IRAS, WISE, 2MASS, AKARI four all sky surveys and their infrared star catalogs were selected. Considering the impact of atmospheric dispersion and attenuation, the limiting detection capability of system in 1-3 m, 3-5 m, 8-10 m and the limiting magnitude in corresponding point source catalog was calculated. Searching in catalogs and selected stars which can be observed by system, results show that 4 599 stars in 1-3 m, 125 stars in 3-5 m, 1 stars in 8-10 m were found. This work also provides a theoretical basis for astronomical calibration and infrared star catalog application for domestic ground-based infrared radiation measurement system.
