NICMOS Aperature Corrections

These are the most current values for aperature corrections for each camera / filter combination.
They were derived using the TinyTim Software package v5.0.
NCS era aperture correction were calculated from TinyTim v6.1 images - using the same measurement criteria


Camera 1: Star aperature taken at 0.5 arcsec , Sky @ 2 arcsec
Camera 2: Star aperature taken at 0.5 arcsec , Sky @ 2 arcsec
Camera 3: Star aperature taken at 1.0 arcsec , Sky @ 4 arcsec

All cameras compared to total flux inside 10 arcsec
