msczero: Display, measure coordinates, set WCS zeropoint offsets

Package: msctools

Synopsis

If the specified Mosaic exposure is not in the display it is displayed. The cursor is used to report WCS coordinates (space bar). Pointing at a star and typing 'z' applys a centering to the star data, reports the coordinate based on the current WCS, and queries for a corrected coordinate. The difference between the current and corrected coordinate is used to compute an offset to the current WCS. When 'q' is typed the last offset may be recorded in the parameters for mscwcs for adjusting other exposures and it can be used to update the WCS of the image.
