This is the trending plot for the GIRAFFE QC parameters derived from BIAS frames, fast readout mode.
This mode is operational since the begin of P86 (October 2010). It is used for
Argus observations.
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.
There is sometimes pick noise visible in this readout mode.
Find more information about GIRAFFE BIAS frames
here.
Other QC parameters related to detector properties (like contamination,
linearity, gain) are trended
here.
General information
Click on any of the plots to see a close-up version.
If applicable, the latest values from Paranal ops logs are plotted as blue dots. More information about those values, including a download option, is available in the OPS column.
The latest date is indicated on top of the plot, data points belonging to that date are specially marked.
If configured,
- 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
