Ah, very cool! The power of the coyote graphics is strong with you! :)
By the way do feel free to use my code for any purpose whatsoever -
it's
in the public domain.
The problem I personally have with cg (and this is entirely the fault
of the way IDL manages namespace) is that it can't be run within
solarsoft,
since solarsoft did seem fit to steal some coyote routines (without
renaming
them) so now I have several mutually incompatible version of some
coyote
routines...
Ciao,
Paolo
