PIONIER news:
2023-02-06 Internal efficiency, median darks are outside KPI which is related to a pump not working. As operations continue, the thresholds have been adapted to show calibratibility and keep track of sudden anomalies.
The Instrumental Visibility and Flux measured on the internal lamp for the different dispersive elements (GRISM, FREE and GRIS+Wollaston). Only the settings with GRISM or FREE are offered for operations.
The Visibility (VIS_) is given for the 6 baselines and the flux (FLUX_) for the 4 PIONIER
input beams.
The saturation limit is above 4000 ADUs.
The low Internal Visibility for the beam combinations including beam 2 is due
to the source.
This plot should be looked at in correlation with the plots showing the fluxes
of the different beams.
The detector polarization voltages (DET.POLAR) are :
High Sensitivity : 7100 mV
Medium_ Sensitivity: 5000 mV
Low_Sensitivity : 1000 mV

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 ↓)
