The Bright Stars page gives a quick overview of current MAPCOR artifact-purge algorithms; the Very Bright Stars page gives a quick overview of current DB_MAPCOR artifact-purge algorithms.  The MAPCOR parameter tuning pages describe how the MAPCOR parameters were determined.

Raymond Tam checked the mapcor parameters after the H band array was swapped in the summer of '99; his summary is found here.

Also, this page describes briefly some cases in which MAPCOR handled saturated star artifacts correctly and DB_MAPCOR was not needed.

Early examinations of PSF mag normalization are discussed in the pages on PSF mag normalization over 11 photometric nights and PSF mag normalization vs. image aspect ratio and shape parameter. Using data from all nights found in the working database, John Gizis is now analyzing the MAPCOR aperture corrections and PSF mag normalizations.

Also, as a side note, the MAPCOR H and K Band Glint Problems page describes the effects of using an incorrect namelist for MAPCOR between 7/30/98 and 8/27/98.
