The routine RD_PNT_HIST will read the file $DIR_GEN_STATUS/pointing.history to
determine all of the spacecraft commanded off-points. The structure returned has
the .TIME and .DAY when the pointing change has occurred, and the offset (.OFFSET)
for that pointing change. The S/C pointing bias is taken into account (the pointing
bias has not been changed since 28-Oct-91).
A sample call is:
IDL> rd_pnt_hist, pntdata
PR_PNT_HIST provides
a simple method to display a summary of the commanded spacecraft pointing changes.
Sample calls are:
IDL> pr_pnt_hist
IDL> pr_pnt_hist, outfil='pr_pnt_hist.txt'
The routine SXT_CMD_PNT will return the SXT pixel coordinates of the
center of the sun using the spacecraft commanded pointing history database file
(calls to SXT_CEN with the 
switch simply call SXT_CMD_PNT). A sample
call is:
IDL> xy = sxt_cmd_pnt(index)
