This plot
This is the trending plot monitoring the stability of the GIRAFFE high-resolution and low-resolution grating.
It measures the thermal and non-thermal drifts of the gratings.
These data are derived from the daily SIMLAMP,TAL health check measurements
(HR grating: H525.8B setting; LR grating: L543.1).
Panel 1 (plots 1-3), top to bottom:
- plot 1: temperature T53
- plot 2: Medusa1, differential drift DX (in pix) against a reference frame, HR
grating
- plot 3: same, for LR grating.
Panel 2 (plots 4-6). Same as panel 1, for shifts in Y direction. The
T53 plot is repeated.
Plots 7,8: Correlation plots DT vs. DX.
The thermal drifts show up as diagonal clustering (upper left to lower right).
Any systematic deviation is due to a non-thermal effect.
Plots 9,10: same for DT vs. DY.
Find more information here.
Note: These data are currently transferred to QC Garching and processed there, no PSO values exist.
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
