I'd be very surprised if this wasn't the kerning table. This table would usually be two bytes per character (ergo 256 bytes, representing a 16 bit twos complement kern value.) I'm surprised this isn't in the character data portion, but I have learned not to ask questions of Xerox's wisdom. The kern table would be mostly 0 (always 0 for fixed width fonts), and I think you would find letters like i and l would have entries in non-fixed ones.
