The lamp flux [ ADU/sec] and the flat counts are monitored in NIR-arm
calibration flat frames. They are composed of ten raw
frames (five on-lamp frames and five off-lamp frames).
Only frames with slit 0.9x11 are scored.
For more information see the
plot tutorial page.
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
