TLDR
The CoLiTec software for the automated search for small celestial objects of the solar system on a series of CCD frames has been developed within the Ukrainian virtual observatory project as mentioned in this paper.Abstract:
The CoLiTec software for the automated search for small celestial objects of the solar system on a series of CCD frames has been developed within the Ukrainian virtual observatory project. Four comets and more than a thousand asteroids were discovered using the software. It was also used to send approximately 700000 positional CCD measurements to the Minor Planet Center. In this paper, accuracy factors of positional CCD measurements using the CoLiTec software are analyzed according to data from the Minor Planet Center. The comparative analysis of these factors according to the results of the processing of the same frames using CoLiTec and Astrometrica software is also conducted. In the case of low signal to noise ratios, the standard deviation of positional CCD measurements using the Astrometrica software is 30–50% greater than that of the CoLiTec software.read more

TL;DR: In this paper, a subpixel Gaussian model of a discrete object image is used to estimate the coordinates of the pixels in a CCD frame, where the coordinate distribution of the photons hitting a pixel is known a priori, while associated parameters are determined from a real digital object image.
