Gain calibration errors at the NCP subtraction step. The top and bottom panels show the errors in the amplitude and phase of the gain solutions, respectively. The dashed lines correspond to the solutions obtained using 2 MHz smoothing while the solid lines correspond to those obtained using 6 MHz smoothing. The thick solid lines show the beam factor and are to be read using the vertical axis on the right-hand side. The different colors refer to the gains in the direction of the different clusters.
