... The program omatt, which calculates the equatorial coordinates of the sources, can in fact calculate these offsets and correct the positions, but only if it has access to a star catalogue. Unfortunately, at present no catalogue is available and hence no correction can be applied. It is hoped that in the near future a catalogue will be provided with each ODF set, enabling an astrometric correction to be made. Figure 1: The OM IMAGING CHAIN . ...
