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.

PARAMETERS

infile [string]
Name of input offset file

outfile [string]
Name of output file

teldef [string]
Name of teldef calibration file

(deltaxcol = DELTADETX) [string]
Column name for change in detector X coordinate

(deltaycol = DELTADETY) [string]
Column name for change in detector Y coordinate

(history = yes) [boolean]
Write HISTORY keywords to output?

(chatter = 3) [integer]
Chatter level [0-5]
