Provide fit diagnostics #2

Open Lyalpha opened 6 years ago

Lyalpha commented 6 years ago

Use the remaining coordinate residuals (after affine+spline transformation) to determine some form of 'goodness' statistic for the transformation.

Add a results method that provides feedback on:

shift, scale, rotation
min/median/max spline shifts in x and y
rms of the transformed coordinate residual offsets With option to plot:
Images of the x and y spline surfaces
An image of the residual offsets to see the spatial dependence.
