It's not any IDL program, but check out g3data at:
http://www.physics.helsinki.fi/~frantz/software/g3data.html
It should do what you want. It looks like it was mainly written for Linux
but it will probably compile under most Unix platforms if you have gtk
installed. I have compiled it for IRIX 6.5
Hope that helps,
