NUMBER: 546 MODULE: mscred.ccdproc, mscred.mscmerge SYSTEM: -V4.8: May 11, 2004 DATE: Fri Apr 15 16:55:02 MST 2005 FROM: valdes BUG: CCDPROC produces a 'Pixel subscript out of bounds' error when applying calibrations produced from binned and merged data. In other words, mosaic data with multiple amplifiers per CCD, which are taken with binning, will produce this error after running ZEROCOMBINE with merging enabled and applying this calibration to flat fields or objects. This problem is caused by CCDPROC incorrectly updating the physical WCS for binned data. This causes the merging of multiple amplifiers to produce incorrect section keywords. This is particularly important for the CCDSEC keyword. Attempting to apply merged calibrations with the invalid CCDSEC keyword causes the error. There are two workarounds. One is to not merge the amplifiers at all or until all calibrations have been applied. The other is to edit the CCDSEC keywords for merged calibration images produced by ZEROCOMBINE and FLATCOMBINE to reflect the true CCD section. The error is normally that the first pixel in CCDSEC is zero rather than one. STATUS: Fixed for the next release of MSCRED.
