Amplitude and phase

This is a straightforward operation that will copy the cubic spline or polynomial coefficients from each IF from memory to the relevant calibration section (-29 or -31, see Table 2) of the hpb file (provided it was initialized at hpb creation). One can override this default by forcing it to use a given sideband or polarisation (or average of sidebands or polarisations) to calibrate both polars/sidebands.
