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

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

Observation when masking pixels A few pixels in region 2 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?
