Pipeline processing

The processing operations listed below have been applied to the reduced data using IRAF for the overall structure, but with supplementary extra stages as indicated. Most reduced data frames have been converted back to unsigned two byte integer format to save on transfer and long term storage requirements, however, reduced short exposure photometric standard frames are stored in four byte real format due to the presence of -ve pixel intensity values.
