This is the FULL trending plot for the GIRAFFE QC parameters derived from BIAS frames. Only 'normal' readmode
is displayed here.
These plots describe:
1. the BIAS level in masterbias frames,
2. the read noise (RON) of a single raw frame,
3. the read noise (RON) of a master frame,
4. the collapsed structure of a masterbias in X direction,
5. the collapsed structure in Y direction,
6. the number of bad pixels.
The label 'new' refers to the CCD replacement in May 2008.
Corresponding data from the GIRAFFE master calibration (re)processing project are available for the first two years and are marked separately.
Find more information about GIRAFFE BIAS frames
here.
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
