H band shows a clear concentration of missing aperture photometry measurements due to dead pixels.
These plots clearly show h band is on thin ice. The following images show the H band coverage map for a few panels of a typical coadd. Two to four internal coadd pixels per panel have less than 2 coverages. John Fowler has investigated these pixels to see if any were marginal and could be turned back on with a minor threshold adjustment. This page last updated on Dec.01, 1998.
