Not nearly enough information provided to make this answerable in my opinion. And even if you did, it's such a specific question, I sincerely doubt it would be useful to anyone else. – MrCranky Jun 5 '12 at 11:35
Without any more information, Some variables and nothing more mean nothing to us. Is this the code you are using? j2me-chess.googlecode.com/svn/tags/2010/1/src/chess – Cyral Jun 5 '12 at 12:24
I even doubt it would be useful to yourself! – Gajoo Jun 5 '12 at 12:54

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, see the FAQ.

I'm guessing it is the Manhattan distance to the center in a program that uses an 0x88 board representation (that's why it's 16x16).

It's actually 241 cells. But according to to the original source code it is indeed a lookup table for the Manhattan distance between two squares on a 0x88 board. – Sam Hocevar Jun 5 '12 at 12:27
