I waited to gather the opinions of several VLBA experts. They say that ICHANSEL should NOT select all channels in ACSCL. The edge channels are often not reliable after bandpass calibration. With a DDC backend (the current one) one can use 89% of the band as reliable. With the PFB backend (the old one but still available) 75% (the default) is just about right. Using 75% with DDC should give about the same results.<br></div><div><br></div>
