(KFISP) Kottamia Faint Imaging Spectro-Polarimeter: Software, motion control, performance and results

摘要

The Kottamia Faint Imaging Spectro-Polarimeter (KFISP) has been recently developed, commissioned and mounted to the Cassegrain focus of the 1.88m telescope at Kottamia astronomical observatory, Egypt. The KFISP instrument demagnified the Kottamia 1.88m telescope Cassegrain focus from a f/18 with a plate scale 6.09"/mm to f/6.14 with a plate scale of 17.87mm. A liquid Nitrogen cooled CCD camera with a 2048×2048 pixels and 13.5-micron square pixel size is fixed to the KFISP through an integrated camera lens. In this paper we describe the camera system, performance, and its software control. As well, KFISP motion control and its software will be introduced. In addition, detailed description of the instrument performance and the results obtained from its operation will be presented.
