Due to low correlated power with RCP in DAS1, we have switched polarisations by changing “abphase” from -90 (normal) to +90 (swapped). This means we recorded channels 3,4,7,8 (instead of 1,2,5,6). This has fixed the problem, suggesting the problem is either in one channel of the DAS1 tied array box, or in the DAS itself.
