NOTE: The Health Check and calChecker services are moved to qcFlow on an instrument by instrument basis. The current pages will not be updated any longer once the move has been finished.
The links to KMOS, UVES, and ESPRESSO have been moved to a new section (qcFlow operational) at the lower part of the navigation bar.
These plots show the difference at a given ref_level between the flux
obtained from 2nd order polynomial fit of flux vs. exposure time and
the flux predicted by the linear term only, normalized by the polynomial flux.
Since data taken after 2009-10 rarely reach 60000 ADU we changed this
ref_level from 60000 ADU to 40000 ADU, starting 2009-10. More information can be found on
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
