Mosaiced images

Please note that for mosaiced sky-images no coincidence-loss corrections will be applied to the count-rates. Hence the accuracy of the photometry of sources with raw-count rates $>$ 5 counts per second will start to decrease, as this neglected correction becomes larger. The units of the semi-major/minor axes will also be in arcsecs.
