SYSTEM: V2.10.3BETA
NUMBER: 275 MODULE: apnormalize SYSTEM: V2.10.3BETA DATE: Fri Jan 27 17:16:35 MST 1995 FROM: valdes BUG: In bug numbers 171 and 225 it was noted that when using variance weighting or cleaning in APNORMALIZE the result would end up scaled by the gain value. The fix was to divide the result by the gain. However, the default parameters for APNORMALIZE do not call for variance weighting or cleaning and so the gain and readnoise are not read. The uninitialized value of the gain used to divide the result of APNORMALIZE is zero causing a divide by zero error. The workaround is to set the weights paraemter to 'variance'. The actually weighting and gain and readnoise parameters are not important to this algorithm. STATUS: This only affects version V2.10.3BETA and will be fixed in later versions.
