Out of curiosity, is there a list cross-referencing the bits used in the stock Nova scenario or a way to cross-reference them with another program (say, MC)? For instance, if I am looking at an outfit, and it gives the availability bits, is there any way to find out which mission/cron/etc. sets that bit without manually opening each mission?

You can't tell where they're used, but I have this handy PDF that tells you all sorts of stuff.

Download MissionBitmap Carbon and run it on a folder containing the Nova Data files in npïf format.
