This is the Health Check plot to monitor the system efficiency of
GIRAFFE, with all data plotted on a chromatic scale (wavelength in nm).
Find more about the efficiency monitoring here.
We display the QC1 parameter mean_effic
(the ratio of detected
photons and incident photons) versus wavelength, for the HR and LR gratings
separately. The green circles mark some of the ETC predictions.
The top row has data for the old CCD (used until 2008-03-13); the bottom row
shows the new CCD (in operations since 2008-05-14).
The ETC values still refer to the old CCD.
General information
Click on any of the plots to see a close-up version.
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
