E.g. within MIDAS a command to remove cosmic rays already exists. Hence, this command can be implemented in the standard CCD pipeline procedure. After the data have been calibrated, one might need to combine a number of science frames into a combined frame. A tool for doing this should correct for possible differences in sky background, exposure time, positions, etc. In a previous version of the CCD context such a tool did exist. We might consider porting this tool to the new CCD context. <P> <BR><HR> <ADDRESS> <I>Petra Nass</I> <BR><I>1999-06-15</I> </ADDRESS> </BODY> </HTML>
