TimePix Threshold CalibrationCalibrates the 4-bit (16 level) Threshold Offsets for eachpixel. The RED histogram is the distribution of noise turn-onpoints with all bits set to high. The BLUE histogram is thecorresponding low setting. The BLACK histogram is thecorrected result. Each channel is ~20 e - …WRMISS – 2012 Austin, TexasPinsky – September 5, 2012.10
