This plot
This is the trending plot for the ISAAC arc lamp calibrations of the SW-arm,
LR-grating
Optical distorion coefficients for setup SW, LR, SH
as derived from the arc recipe. The value DeltaX is given by :
Delta X = a + b * x + c * y + d * x*x + e * y*y + f * x*y - x
These plots describe:
1. coefficient a, the offset in x
2. coefficient b, linear term for x
3. coefficient c, linear term for y
4. coefficient d, x square term
5. coefficient e, y square term
6. coefficient f, mixed higher order term
Find more information about ISAAC QC parameters derived from arc lamp frames
here.
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 OPSLOG section on top of the page.
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
