Pads for probe cards in ALICE-D2       /05.03.2000/
(X,Y) coordinates are quoted in microns and referred to the centers of 
bonding pads. (0, 0) corrispond to the center of the detector.
Convention: 
left is for negative X, right is for positive X;
DOWN half is for negative Y, UP half is for positive Y.

Detector size: X= 87588 micrometers; Y= 72500 micrometers. 
Detector corners:
  LEFT UP: (-43794, 36250)
RIGHT UP:  (43794, 36250)
 LEFT DOWN: (-43794, -36250)

	Anodes (n-side)
There are 256 anodes to be bonded to the inputs of front-end electronics. In 
addition there are 2 anodes (one at the left edge and one at the right edge 
of the anode array) that have to be bonded to the ground. I call these 2 
anodes #L and #R. The pitch of all anodes is 294 micrometers.
