This is a image header representation of a tangent plane projection plus non-linear distortion terms. The NOAO Mosaic Data Capture Agent will produce the new WCS during future observations. The WCS registration includes scale and rotation adjustments which correct for differences due to atmospheric refraction. September 1997 First user and mosaic developer evaluation version with minimal documentation. August 1997 A better prototype.
Help is skimpy.
Only mscguide and imtextensions have help. This is a prototype. For NOAO Mosaic Imager data a separate instrument database distribution also needs to be installed. The package may be installed for a site or as a personal installation. In the following steps you will need to know the IRAF architecture identifier for your IRAF installation.
