A new method based on the subpixel Gaussian model for accurate estimation of asteroid coordinates
V. E. Savanevych, O. B. Briukhovetskyi, N. S. Sokovikova +8
We describe a new iteration method to estimate asteroid coordinates, which is based on the subpixel Gaussian model of a discrete object image. The method operates by continuous par…
