It prints their locations in the message window. It counts the number of NaNs in a vis record (1 baseline, 1 time, all polarizations, spectral channels, and IFs). It counts real and imaginary part separately and so is likely to count 2 for every complex vis that has gone bad. Adverbs: INNAME.....Input UV file name (name). Standard defaults. INCLASS....Input UV file name (class). Standard defaults. INSEQ......Input UV file name (seq. #). 0 => highest. INDISK.....Disk drive # of input UV file. 0 => any. BCOUNT.....Start visibility number for search. 0 -> 1. ECOUNT.....Stop printing after ECOUNT lines - 0 -> 1000. ----------------------------------------------------------------
