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

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
