This plot
This is the trending plot for the ISAAC
QC parameters derived from long wavelength arm (LW) spectroscopic flat frames.
These plots describe:
1. dark subtracted counts of the master spectroscopic flat LW-LR-SL (3.55 um), all slits.
2. dark subtracted counts of the master spectroscopic flat LW-LR-M (4.75 um), all slits.
3. dark subtracted counts of the master spectroscopic flat LW-MR-SL, all slits.
4. dark subtracted counts of the master spectroscopic flat LW-MR-M, all slits.
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
