Hi Bob,

I got a comment a while back (I think it might have been on this
list) that on black and white printouts, the difference between orange
and yellow triangles got lost. So I switched to having shadowed
satellites be hollow triangles, and sunlit ones be filled.

You can get the orange triangles back by adding the following line
to 'guide.dat':

SHADOWED_SATELLITE=C0080ff;f3;-15,-7;15,-7;0,15;

(Or you can hit Alt-J and enter the above text.)

If you change the 'f3' to 'k3', the triangle will be drawn as an
unfilled orange shape. That way, you'll have the different color
on-screen _and_ the filled/unfilled difference on printouts.

The above line essentially describes the symbol used for drawing
shadowed sats. Its meaning is not quite as obscure as it might seem;
it's the same system used for symbols in user-added datasets, and is
described a bit at

If you change the 'f3;' to 'k3;', the triangle will be drawn as an
unfilled orange shape. That way, you'll have the different color
on-screen _and_ the filled/unfilled difference on printouts.
