<p>I found the bug in FITLD that explains the bad auto-correlation values. A MNJ on 31DEC19 or 31DEC20 now will get you a corrected version. It was scaling old VLBA hardware correlator data incorrectly.</p>
<p>I tried VLBAFIX and it split out FQ 1 and ran FIXPOL on it. The other FQIds were not split out. That will require investigation (VLBAFIX is not simple).</p>
<p>But ACCOR ran fine on both a Linux and a Mac system. Perhaps you want to mv $LOAD/ACCOR.EXE to some dummy name before running the MNJ. That will cause a new copy to be downloaded.</p>
