<p>I do not know why your ACCOR is failing. I just downloaded your data from the archive and ran ACCOR on the U band data and it ran fine. BUT your auto-cor data for all 4 frequency groups have amplitudes over 100000 - they should be near 1. Your Xcor data have amplitudes like 0.001 before ACCOR and after more like 1.e-9. I have asked some more expert people about this but I think something is not right.</p>
