NUMBER: 487 MODULE: ccdproc SYSTEM: V2.11 DATE: Thu Jul 5 08:35:00 MST 2001 FROM: valdes BUG: When applying a dark count correction, the dark count calibration image is scaled to the data being calibrated using the ratio of the dark times. The dark time for an image is the 'darktime' keyword and if this is absent 'exptime', where these may be translated to other keywords if a translation is given in the instrument file. When a value for the dark time is found it is used without checking for zero values. Therefore, if the dark count image has a dark time value of zero a floating divide or floating exception will occur. The workaround is to edit the header to add the appropriate values. STATUS: In the next release an appropriate error message will be given.
