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:
 
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. V filter,   DIT, NDIT = 4.0, 10
 N_R filter, DIT, NDIT = 2.0, 20
 N_I filter, DIT, NDIT = 2.0, 40
 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
