ICRF CCD Images Data-Base - Methods of Image Processing
Abstract
The astrometric division of Astronomical Institute of the Romanian Academy begun the observations for connecting optical and radio reference systems. We obtained till now, a significant amount of astronomical data which will became our new CCD Images Data-Base regarding ICRF extra-galactic radio-sources. The drawback of narrow-field observations was overcome by using overlapping FITS frames, in order to include in the final image enough reference stars to compute an accurate plate solution. The paper shows the methods of stacking and overlapping images with application to open clusters used as astrometry calibration regions.
