[daip] PCCOR issue.

[Craig Walker]

I have loaded my BW107A (M87) data to AIPS on noatak (work Linux box). 
I ran VLBAPCOR on it and got no solutions, or at least none in the first 
couple hundred SN table entries.  The data were NaNs and some Infs.  On 
my Mac at home, there were some solutions, but most were failures.  I 
haven't traced the difference yet.

So the data are on the local net.  Machine is NOATAK.  Disk 1 
(/DATA/NOATAK_1).  User 607.  There is only one file there.  The output 
was SN 1 and CL 2.  The file is multiple GB.
