  ABSTRACT: Since 1997, SCUBA has produce large amounts of data which have been archived online. To produce a calibrated image, the user will usually need to perform several tasks and this can be daunting for new users. XORACDR has provided an easy graphical interface for the user, but it can still be restrictive. In 2000, Doug Johnstone published a paper which showed the Matrix Inversion (MI) method which, though more time consuming, produces better results than the Emerson2 (EM2) method currently used by ORACDR.

In the last 12 weeks, I have made adjustments to Doug's code to make it more user friendly. I have also integrated it with a Perl Script which will take raw data files and produce calibrated image automatically. The test has been performed on a number of well known objects and the results were compared to EM2 for a few cases.
