This plot show the optiocal distortion coefficient X_1_0 and Y_0_1 as a function of the IFS bench temperature.
The polynomial to correct the shifts in x direction is:
Delta X = X_0_0 + X_1_0 * x + X_0_1 * y + X_1_1 * x * y + ...
and for the shifts in y-direction:
Delta Y = Y_0_0 + Y_1_0 * x + Y_0_1 * y + Y_1_1 * x * y + ...
Hence X_1_0 is the first order linear scale (the plate scale) in x-direction and
Y_0_1 is the first order scale in y-direction.

Click on any of the plots to see a close-up version.
The latest date is indicated on top of the plot.
If configured,
- data points belonging to the latest date are specially marked
- 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
