This plot

This is the trending report for the UVES thermal compensations. It is based on daily FMTCHK calibrations.

Each camera (BLUE and RED) of UVES has a thermal compensation system (this was installed in December 2001). These plots present the residuals of the fitted lines of the FMTCHK calibrations with respect to the physical model as a function of temperature. Ideally if the thermal compensation was working perfectly the gradients would all be zero. However because the system is delicate to adjust there might be residual gradients which are calculated and monitored here.

As a rule of thumb the gradients should be smaller than 0.3 px/K. If the correlation plots show wild variations or a bifurcal distribution, this most likely reflects a readjustment, or a non-thermal shift (e.g. by an earthquake), during the plotted date range.

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
