NAME

astrom - determines World Coordinate System coordinates

SYNOPSIS

astrom coord_list [debug] [crpix1=] [crpix2=] [skew] [mirror] [equinox=] [residuals]

DESCRIPTION

Use astrom determines the astrometric conversion between the rows and columns in an image and the RA and Dec of the stars. The program compares two lists, the starlist or row/columns which comes in standard input and the coordinate list which must be the first argument. Both lists must have the same number of members and be collated.

OPTIONS

crpix1 - sets the CRPIX1 value.

crpix2 - sets the CRPIX2 value.

skew - allows the full rotation matrix to be solved rather than the scale factor, rotation angle matrix. Use this option if you suspect the pixel scales are different in row and column.

mirror - sets the determininant to be -1.

residuals - prints out angular residuals from fit.
