10 Region CK (selection) 100u 0 12 3 4 56 7 8

11 Life from the samplers Lamp saturates pixels in small ~8x8 pxl region

12 Life from the samplers Mask eliminates all hits except a 10x10 region where the laser is known to be Two laser positions + non-laser refernce

13 Observation when masking pixels A few pixels in region2 showed hits despite being masked… was always the same ones Should probably make a list of bad pixels with a full mask and apply in post-processing?

14 A fine scan of shaper pixels (samplers were masked during these runs) Laser fired at points in a line with 10 micron separation 10u 0 1 2 3 4 5 6 7 8

15 A fine scan of shaper pixels (samplers were masked during these runs) Laser fired at points in a region with 10 micron separation 10u 8
