NAME
det2att - Converts detector coordinate offsets to rotations
USAGE
det2att teldef=<string>
outfile=<string>
infile=<string>
DESCRIPTION
This tool calculates the spacecraft rotation corresponding to
offsets in detector coordinates.
The sense of the rotation qdelta for an offset dx, dy is such if
a detector position p is mapped to sky coordinates using an attitude
q0, then applying qdelta * q0 to p results in the same sky position as
applying q0 to p - dx, dy.
