This plot
This is the trending plot for the ISAAC
science spectra.
For the setup : SW-MR-SK
These plots describe:
Fig. 1. average intensity in ADU
Fig. 2. central wavelength derived from sky line wavelength dispersion solution
Fig. 3. correlation factor of sky line wavelength dispersion solution (>50% is good).
Fig. 4. Grating offset with respect to day-time arc calibrations
Details are given on the ISAAC science spectra page.
General information
Click on any of the plots to see a close-up version.
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
