This plot
This is the trending report for the quality of the UVES Echelle wavelength
calibration. It is based on QC
parameters derived from WAVE_ECH frames.
This report presents the first (summary A) of two sets of detailed parameters. Data
are
for the BLUE 437, 1x1,
0.4 arcs setting.
The individual plots describe:
- the minimum wavelength of the solution. Changes of a few nm
usually occur because of changes in the last detected line, which
often happens when the position of the orders changes slightly (see
Grating Position trending).
Changes of tens-hundreds of nm are usually due to the pipeline failing
to locate entire orders.
- the minimum order found in the solution.
(The minimum order
is available in the QC1 database only since 2011-05-05.)
- The average of the residuals of the lines used in the final
solution with respect to their laboratory wavelengths.
- the maximum wavelength of the solution (see also remark for the minimum
wavelength)
- the maximum order found in the solution.
- the RMS of the residuals of the lines used in the final solution with
respect to their laboratory wavelengths.

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
