New Skills and New Knowledge: Training
Calibrate positions of all nodes
 At each node, the isocrystal is
scanned in a grid pattern
perpendicular to the incident
beam
 Light intensity map is recorded
 Two 5 x 5 grids (coarse and fine)
 The calibrated node corresponds
to the center of the light intensity
map
 Must be performed separately for
fixed cones and IRIS
 Result: Node “error list”1
