It is possible to make a simple display of the sun and to overlay the
box showing the field of view size and location by using PLOT_FOV
if you have the index, roadmap or observing log structures.
A sample call is:
IDL> plot_fov, index, /box
If you don't have a PFI structure, then you can use the routine PFI_LOC.
It can accept a date and time and will display a simple plot of the
sun and the SXT PFI location (PFI_LOC simply reads the observing log
and then calls PLOT_FOV). Some sample calls are
IDL> pfi_loc, '23-jun-93 1:00'
IDL> pfi_loc, timstr, hours=2
The second example will display all of the different PFI locations for
the time stored in the string variable timstr 
2 hours.
