CoLiTec published article in Open European Journal on Variable Stars

CoLiTec Team published new article “FrameSmooth software – new tool for the calibration of astronomical images” in «Open European Journal on Variable Stars», which is included in the science database of NASA – Astrophysics Data System (ADS).

The traditional procedure of image calibration in differential photometry is based on correction for dark-frame and flat-field. This approach don’t remove big scale non-uniformities in the detector illumination caused by Moonlight or other scattered light. This can be corrected by mathematical methods. Ukrainian developers of CoLiTec software use inverse median filter for astrometric tasks. We have tested the possibility to use it for photometry also. The answer is generally positive. There is a chance to skip the flat-field calibration in some cases. We present the FrameSmooth software which performs different image calibration procedures and also able to operate in fully automatic mode.
