This plot

This is the trending report for UVES QC parameters derived from standard star observations.

UVES flux standard stars are observed for two purposes: for flux calibration, with a frequency of approximately once per 3 days during nighttime, and for system efficiency monitoring approximately once per 14 days. In both cases observations are made in 3 dichroic settings: DI1 346+580, DI1 390+564 and DIC#2 437+860. The CCD readout mode is always 225kHz,1x1,low. Observations are made with a 5 or a 10 arcsec slit. The measured efficiency is then the maximum efficiency at the center of an order closest to the central wavelength of the wavelength setting.

The individual plots describe the measured efficiency for the three wavelength settings 346, 390 and 437 nm.

These reports are not scored since an outlier might be due to bad atmospheric conditions rather than indicate an issue with the instrument. Interpretation of the reports requires knowledge of the actual conditions during the night.

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
