论文摘要
Cagire是Colibrí机器人望远镜的近红外摄像头,旨在跟踪SVOM警报。它基于从Lynred French Company的Alfa 2K x 2K检测器,以“向上坡道”模式运行。观察结果包括一系列短(1-2分钟)的暴露,在此期间每1.3秒读出像素,同时持续地与接收的磁通成比例地积累了费用。我们在这里讨论Cagire数据的预处理以及可用于恢复每个像素从坡道斜率收到的通量的方法。
CAGIRE is the near infrared camera of the Colibrí robotic telescope, designed for the follow-up of SVOM alerts. It is based on the ALFA 2k x 2k detector, from the LYNRED French Company, operating in "Up the Ramp" mode. An observation consists in a series of short (1-2 minutes) exposures during which the pixels are read out every 1.3 second, while continuously accumulating charges proportionally to the received flux. We discuss here the preprocessing of CAGIRE data and a method that can be used to recover the flux received by each pixel from the slope of the ramp.
