Life from the samplers

Lamp saturates pixels in small ~8x8 pxl region

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

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?

A fine scan of shaper pixels

(samplers were masked during these runs)

Laser fired at points in a line with 10 micron separation
