Most of the BIAS observations are taken with 5 files in the template. The user manual values (in e-) are:

1. plot1: 4.1 BLUE fast read-out low gain 225kHz/lg
2. plot2: 4.2 RED EEV (CHIPL CCD-44 CHIP2) fast read-out low gain 225kHz/lg
3. plot3: 3.7 RED MIT (CHIPU CCD-20 CHIP1) fast read-out low gain 225kHz/lg
4. plot4: 2.1 BLUE slow read-out high gain 50kHz/hg
5. plot5: 2.8 RED EEV slow read-out high gain 50kHz/hg
6. plot6: 2.1 RED MIT slow read-out high gain 50kHz/hg
7. no value for BLUE ultra fast read-out low gain 625kHz/lg
8. plot9: 4.3 RED EEV ultra fast read-out low gain 625kHz/lg
9. plot8: 4.7 RED MIT ultra fast read-out low gain 625kHz/lg
   The thresholds are set as -+10% of nominal values (from the KPI document).

   These nominal values are (in ADU)

   • BLUE 1x1 1.11
   • REDL 1x1 1.57
   • REDU 1x1 1.47
   • BLUE 2x2 2.21
   • REDL 2x2 2.93
   • REDU 2x2 2.63
   The e- to ADU conversion used are
   • BLUE 1x1 1.84 ADU
   • REDL 1x1 1.59 ADU
   • REDU 1x1 1.46 ADU
   • BLUE 2x2 0.54 ADU
   • REDL 2x2 0.52 ADU
   • REDU 2x2 0.52 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
