用AKARI上的红外照相机（IRC）进行慢扫描观测
Slow-scan Observations with the Infrared Camera (IRC) on-board AKARI
摘要：
我们提出的表征和校准的慢扫描观测模式的红外相机（IRC）上的AKARI。IRC慢扫描观察在S9 W（9 $μ$ m）和L18 W（18 $μ$ m）波段进行。我们已经开发了一个工具包的IRC慢扫描观测数据减少。我们引入了一种“自指向重建”的方法，以提高定位精度高达1”。点扩散函数的大小在S9 W波段为$\sim6"$，在L18 W波段为$\sim7"$。分别用3颗和4颗红外标准星在S9W和L18W波段的观测数据进行了流量定标。与AKARI IRC PSC和WISE初步目录相比，通量不确定性估计优于20%。
英文摘要：
We present the characterization and calibration of the slow-scan observation mode of the Infrared Camera (IRC) on-board AKARI. The IRC slow-scan observations were operated at the S9W (9 $μ$m) and L18W (18 $μ$m) bands. We have developed a toolkit for data reduction of the IRC slow-scan observations. We introduced a "self-pointing reconstruction" method to improve the positional accuracy to as good as 1". The sizes of the point spread functions were derived to be $\sim6"$ at the S9W band and $\sim7"$ at the L18W bands in full width at half maximum. The flux calibrations were achieved with the observations of 3 and 4 infrared standard stars at the S9W and L18W bands, respectively. The flux uncertainties are estimated to be better than 20% from comparisons with the AKARI IRC PSC and the WISE preliminary catalog.
