Actually the LISTR outputs are phase stopping position not pointing
position. The best way - if you have an image made at the pointing
position (no shift - use iMHEADER to make sure).
GETN i
keyw='crval1'; geth
keyw = 'OBSRA'
puth
getn j2 ; puth
getn j3 ; puth
getn j4 ; puth
GETN i
keyv='crval2'; geth
keyw = 'obsdec';
puth
getn j2 ; puth
getn j3 ; puth
getn j4 ; puth
where i is the image at the pointing position and j2, j3, j4 are the 3
other images missing the pointing position.
The new verb CODECIMAL allows you to convert between COORDIN in
sexagesimal and X and Y in decimal is you end up having to enter the
values from the LISTR output.
