Abstract:
We have developed a system to process raw IRAS Pointed Observation (PO) data,
using software developed at the Laboratory for Space Research, Groningen,
The Netherlands. Several PO's can be coadded into one image. As an example
we processed 99 PO's in the Chamaeleon I molecular cloud in to one image
for every IRAS band. The list of extracted point sources contains some 300
new IRAS sources, down to a flux level of 21mJy at 12um.
