Wavelength calibration: trending of dispersion (in 10E-3 nm/pixel).
Dispersion is monitored for the two daily health check settings
with reference wavelength (on chip 3) of 1090.4nm using ThAr lamp and 4092.9nm
using N2O absorption cell.
Chips 1 and 4 of the 1090.4 nm setting suffer from vignetting.
Pipeline results are arbitrary and are not plotted.
Pipeline processing in Garching applies dark subtraction and flat-fielding.
This can result in differences for the dispersion. Paranal results for some detectors
are, therefore, omitted.
General information
Click on any of the plots to see a close-up version.
If applicable, the latest values from Paranal ops logs are plotted as blue dots. More information about those values, including a download option, is available in the OPS column.
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 ↓)
- you can download the data for each parameter set if the 'Data downloads' link shows up
