国内已知的红外星库数量有限,辐射照度、覆盖波段范围小,分布密集度低,无法满足现有地基红外辐射测量系统天文标定的需要。根据系统的探测波段考察并选取IRAS、2MASS、WISE、AKARI4个全空域巡天计划及其生成的红外星表。综合考虑大气弥散、大气衰减的影响,分析计算系统在短波红外1~3μm、中波红外3~5μm、长波红外8~10μm的极限探测能力及在对应点源星表中的最低可探测的星等。搜索选取可供系统观测的恒星,结果显示在短波选取4 599个恒星目标,中波选取125个恒星目标,长波选取1个恒星目标,为我国现有地基红外辐射测量系统天文标定及红外星表进一步应用提供理论依据。
There are a limited number of domestically known infrared galaxies, which have low radiation irradiance, small coverage band and low distribution density, which can not meet the needs of astronomical calibration of existing ground-based infrared radiation measurement systems. According to the system of detection bands and select IRAS, 2MASS, WISE, AKARI four airspace survey program and the resulting infrared satellite table. Considering the influence of atmospheric dispersion and atmospheric attenuation, the limit detection ability of short-wave infrared 1 ~ 3μm, medium-wave infrared 3 ~ 5μm, long wave infrared 8 ~ 10μm and the lowest detectable star Wait. The results show that 4 599 stellar targets are selected in the shortwave, 125 stellar targets are selected in the midwave, 1 stellar target is selected in the longwave, which can be used for astronomical calibration and infrared catalog of the existing ground-based infrared radiation measuring system Provide further theoretical basis.
