Abstract
The position sensitive detector of the SIGMA telescope, a variety of the Anger camera, suffers from intrinsic non uniformity defects. In order to maximize the signal to noise ratio of the observed gamma ray sources, the removal of the systematic defects should be nearly perfect.
In this paper we describe and give the achieved performances of some correction methods. In particular we describe an adaptative filtering method which is automatically adjusted for the best possible signal to noise ratio.
