Brian, that's not exactly what I'm looking for, but it did point me to
seeing what's contained in the cursor.pro and see if I can explicitly
give the coordinates and work from there. I appreciate your help.

Just for more clarification, I am reading this information from a
netCDF file into IDL and doing a "plots" to draw it over a map_set. I
just want to give the coordinate in the PS (x,y coords) and get the
lat, long, and albedo for that pixel.
