4.4.3.4 Antenna Delays — ’K’ solutions

gaintype=’K’ solves for simple antenna-based single-band delays via Fourier transforms of the spectra on baselines to the reference antenna. This is not a global fringe fit but will be useful for deriving delays from data of reasonable snr. A subsequent bandpass is recommended to describe higher-order channel-dependent variation in the phase (and amplitude).
