Plots that are Readyas of Today
• All are complete for both sensors, n- and p-type.
• Ped and CMS Noise – There are many!– Signal vs channel– Gaussian fits per each sector
• Test Pulse– MPV vs link
• MPV vs Y Position (mm) for 500 V
• Cluster sizes for HV Scan when P type is High Irr
• Efficiencies for HV Scan when P type is High Irr

Plots Not Ready yet
• MPV vs Y Position (mm) for other voltages
• ADC vs Voltage projection, slice of MPV vs Y Position at high irr.
• Cluster sizes for HV Scan when N type is High Irr
• Efficiencies for HV Scan when N type is High Irr
• All are in process.

**Means obtained the same way as the noise, only I pick out the channel that has the signal on it, which I know before hand; plot mean per link.
2 channels are pulsed per link, so 128 channels hit.
