compatibility plots: .to “measure” the agreement of a single measurement with the indirect determination from the fit using all the other inputs:

Color code: agreement between the predicted values and the measurements at better than 1, 2, ...nsigma.//

The cross has the coordinates (x,y)=(central value, error) of the direct measurement
