Hi Eric,
Sorry to both you again but I have been
having some trouble with placing crosses on
high dynamic gryescale images using greys with a starfile. The crosses 
read from
the star file are  white when the background
is white and vice versa. However, I still can't see
some of the crosses (black cross on a not-so-black background and vice 
versa).
What parameter in greys would help me to get the crosses seen better with 
varying background?. I have
tried a couple of things but have not worked out yet.
