NUMBER: 504 MODULE: nproto.objmasks SYSTEM: V2.12-V2.12.1 DATE: Tue Aug 6 16:03:28 MST 2002 FROM: valdes BUG: This task may abort with a floating divide error. This is caused by the first pass estimate of the background sigma using a planar fit. The can produce zero or negative sigma values. The workaround is to set the 'fitxorder' and 'fityorder' parameters to 1 in the hidden parameters set objmasks1; i.e. epar objmasks1. STATUS: In the next release the initial sky will still be fit by a surface of some specified order but the initial sigma will be purely a constant.
