This is the trending report for UVES QC parameters derived from
standard star observations.
As per the
Calibration Plan
standard stars are observed for the purposes of 'Flux Calibration' with
a frequency of approximately once per 3 days during Nighttime/twilight and for
the purposes of 'Efficiency Monitoring' with a frequency of
approximately once per 14 days during Nighttime. In both cases
observations are made in 3 DICHR settings, DIC#1 346+580, DIC#1
390+564 and DIC#2 437+860 and in CCD readout mode
225kHz,1x1,low. Observations are made either with a 5 or 10 arcsec
slit. The measured efficiency is then the maximum efficiency at from
the center of an order closest to the central wavelength of the
wavelength setting.
The individual plots describe:
the measured efficiency for wavelength setting 346 taken with Dichr#1
the measured efficiency for wavelength setting 390 taken with Dichr#1
the measured efficiency for wavelength setting 437 taken with Dichr#2

The latest date is indicated on top of the plot, data points belonging to that date are specially marked.
If configured,
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 ↓)
