Transmission measured on the astronomical calibrators (sky) for the different settings
This is calculated when the H magnitude is available on the calibrator.
All the data are used even when taken in bad atmospheric
conditions.
The UT plot shows the transmission of the UTs
The AT plot shows the transmission of the ATs
For the ATs the colors in the individual plots correspond to the station where
the AT is positionned:
- blue : ATi on Station1
- green: ATi on Sation2
- red: ATi on Station3
- black: ATi on Station4
The throughput of PIONIER is also monitored using an internal lamp (see Daily
Calibrations)
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
