Residuals

Differences between the observed and modeled values:

  • r_i = wrap_angle( angle(solution) - angle(constructed) )
  • angle(solution) is the phase of the calibration solution (input data)
  • angle(constructed) is the phase of the model fit,
  • wrap_angle ensures the phase residuals remain within $[- \pi, \pi]$.

$\chi^2/\text{dof}$
