Example of a 512-pulse stack folded modulo for six radio frequencies within the LBA band. The modfold is repeated twice along the Y -axis to mitigate wrapping, and the corresponding average profile is plotted on top. White circles mark the centres of driftbands obtained from fitting 2D tilted Gaussians. As the radio frequency increases, the driftbands move towards each other both in ϕ (reflecting the behaviour of the average profile components) and in Θ.
