"Set from image" looks to do the right thing. However, "Select area" is
doing something odd. I guess a problem here is that you select a box
aligned with GLON/GLAT on the image, and then that ends up being rotated
in RA/Dec. I suppose this isn't worth much effort, but it would probably
still be good if this mode at least gets the central value right (even if
selecting a box aligned in GLON/GLAT ends up being a box aligned in
RA/DEC)
For example,
at about glon=268 glat=-1 it should give about 9hr -47deg30min
But if I draw a box on the map using "Select Area" over that location I
get
RA 17:51:36 Dec -01:03:48
thanks,
Ed
