This plot

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.  

General information

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
