This plot

The gain is monitored for the full detector (320x255) and for the "science" pixels (26 windows of 6x1 pixels).
Only the gain across the full detector is scored

The gain has been measured after installation of RAPID (december 2014):
Low_Sensitivity:
- det_polar=1000mv gain=1.398 e-/ADU
- det_polar=3000mv gain=0.861 e-/ADU
Medium_Sensitivity:
- det_polar=5000mv gain=0.296 e-/ADU
High Sensitivity:
- det_polar=7100mv gain=0.107 e-/ADU
 


General information

Click on any of the plots to see a close-up version.

The latest date is indicated on top of the plot.

If configured,

  • data points belonging to the latest date are specially marked
  • statistical averages are indicated by a solid line, and thresholds by broken lines
  • outliers are marked by a red asterisk. They are defined as data points outside the threshold lines
  • "aliens" (= data points outside the plot Y limits) are marked by a red arrow ( or )
  • you can download the data for each parameter set if the 'Data downloads' link shows up
