[daip] APCAL can get temperature.

When I try to run APCAL with DOFIT on with some of my M87 43 GHz VLBA
data, I get:
localh> APCAL1: Task APCAL (release of 31DEC08) begins
localh> APCAL1: REAWX: ERROR 6 SOMETHING WRONG WITH WX TABLE
localh> APCAL1: REAWX: WXINI FINDS 0 ROWS, WX TABLE CORRUPT?
localh> APCAL1: TXTWX: ERR 6 OPENING WX TABLE 1
localh> APCAL1: Purports to die of UNNATURAL causes
localh> APCAL1: localhost 31DEC08 TST: Cpu= .0 Real= 0
PRTAB and WETHR both think the table is fine.
When I change to reading the external weather table produced by VLOG,
I get lines like the following from VLOG, probably one pair for each
antenna. The times are about the times of the ends of the observation.
But there does seem to be a lot of data in the file produced.
localh> VLOG 1: ZTXOP2: /Users/cwalker/M87/BW090_Fast/BW090J/BW090J.TSYS

localh> VLOG 1: ***** NO INDEX RECORD FOR LINE STARTING: 072 11:30.60
localh> VLOG 1: ***** NO UNIQUE FREQUENCY MATCH FOUND
When I run APCAL, I get:
localh> APCAL1: Writing SN table 2
localh> APCAL1: REAWX: *** NO TEMPS FOUND IN WX TABLE FOR ANT 1, LEFT AT
0 ***
localh> APCAL1: OV RCP 0/ 8h 1m Trec (K): 83.77 Zen. opac.: .065

localh> APCAL1: Plot file version 1 created

localh> APCAL1: KP RCP 0/ 8h 0m Trec (K): 79.08 Zen. opac.: .053

localh> APCAL1: GFINIS: number records used 142
localh> APCAL1: REAWX: *** NO TEMPS FOUND IN WX TABLE FOR ANT 3, LEFT AT

localh> APCAL1: PT LCP 0/ 8h 0m Trec (K): 72.72 Zen. opac.: .030
localh> APCAL1: Plot file version 2 created
and so forth for all antennas. Since 0C is not all that bad an
approximation of the temperature (except SC), this calibration is probably
not too awful. But still, it should work better!
So what's gone wrong? All this used to work.
I'm on my Mac Powerbook notebook G4 and last ran a midnight job on April 30.
I just tried a midnight job just in case, and got the following
termination messages:
AIPSUPD - ErrorFile is
/Users/aips/31DEC08/MACPPC/UPDATE/UPD20080517.225215.ERR
AIPSUPD - Using CVS for copying files.
AIPSUPD - calling UPDCVS
cvs [update aborted]: connect to mnj.aoc.nrao.edu:2401 failed: Operation
timed out
UPDCVS - cvs update of 31DEC08 had abnormal completion
AIPSUPD - UPDCVS failed, Status=1
Doesn't look good. I did it from home. I guess I'll try from work at
some point. Meanwhile I'll send this message and keep using the April 30
version.
Cheers,
Craig
