This plot monitors the shutter issue, that occured between 2015-09-09 and 2016-06.
The issue is explained on the SPHERE problems page and on the plot tutorial
page for zimpol flats.
Only the polarimetric direction = zero and cycle = odd signal is monitored.
The following setups are covered:
- V filter, DIT, NDIT = 4.0, 10
- N_R filter, DIT, NDIT = 2.0, 20
- N_I filter, DIT, NDIT = 2.0, 40
The plot contains four boxes, which shows the shutter parameter (essentially
the RMS over the NDIT subintegration signals)
for both read modes (SlowPolarimetry and Fastpolarimetry) and for both
detectors.
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
