This is the trending report for the UVES QC parameters derived from BIAS frames.
These plots describe:
- the read noise (RON) of a single raw frame of the BLUE chip in different binnings and gain
- the read noise (RON) of a single raw frame of the REDL chip in different binnings and gain
- the read noise (RON) of a single raw frame of the REDU chip in different binnings and gain
Most of the BIAS observations are taken with 5 files in the template.
The user manual values (in e-) are:
- plot1: 4.1 BLUE fast read-out low gain 225kHz/lg
- plot2: 4.2 RED EEV (CHIPL CCD-44 CHIP2) fast read-out low gain 225kHz/lg
- plot3: 3.7 RED MIT (CHIPU CCD-20 CHIP1) fast read-out low gain 225kHz/lg
- plot4: 2.1 BLUE slow read-out high gain 50kHz/hg
- plot5: 2.8 RED EEV slow read-out high gain 50kHz/hg
- plot6: 2.1 RED MIT slow read-out high gain 50kHz/hg
- no value for BLUE ultra fast read-out low gain 625kHz/lg
- plot9: 4.3 RED EEV ultra fast read-out low gain 625kHz/lg
- 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
