General description: This is a PostScript file that contains a map of the plugging in the focal plane. It should list the plateid, the temperature for drilling, the hourangle, and the MJD tuned for observation. It should show all holes that should be plugged by the same fiber block as a single color connected by lines. It should also show the location of the guide stars (numbered circles) and light traps (big squares). The units on the axes are mm.
