Design and Realization of Photometric Processing Pipeline for 1.26m Infrared Telescope

The 1.26m infrared optical telescope is a telescope system co-constructed by the National Astronomical Observatories and Guangzhou University. Photometry is one of the important means of the telescope observation. However, the data processing for observational data is a significant problem in current system. In order to speed up the processing performance, in this paper, we present a semi-automatic photometric processing pipeline for the 1.2-meter infrared telescope. After obtaining the original data, the pipeline system would rebuild the FITS header information according to the observation log of the day. And then, all the FITS images would be processed automatically including searching star positions, calculating the grow line and FTHW of the stars, computing target magnitude and saving the final results. The pipeline proposed in the study is efficient, convenient and accurate. It combines full complicated and repetitive steps in the current mainstream metering mode into the program so as to save unnecessary labor time, significantly improving work efficiency.
