[daip] Some TECOR questions

[Michael Bietenholz]

I tried running TECOR (31DEC03) and had the following problems:

  TECOR1: ZTXOP2: using translated file name =
  TECOR1: ZTXOP2: /home/michael/ionex/jplg3240.02i
  TECOR1: ZTXOP2: using translated file name =
  TECOR1: ZTXOP2: /home/michael/ionex/jplg3250.02i
  TECOR1: IONMAP: FAULTY INPUT FILE - TIMES OUT OF ORDER
  TECOR1: IONINI: ERROR    3 READING IONEX DATA
  TECOR1: TECION: ERROR    1 INITIALIZING IONEX MODULE
  TECOR1: TECINI: ERROR    2 INITIALIZING IONEX MODULE
  TECOR1: TECOR: FAILED TO INITIALIZE PROGRAM

I've attached the jplg files.  From what I can see these look like
they ARE in time order.  TECOR runs when I copy out only the first day
of the above data set and use only the first of the jplg files.  Same
results with the esag files.

When I got it to run, TECOR filled in values in the dispersive delay
column in the CL table (col. 15).  However, I am puzzled by the
results:

1.  the dispersive delay column (CL col 15) supposedly in secs.  This is
    consistent with AIPS convention

2.  TECOR puts values of a few E-06 into this column, ie. a few micro-secs

3.  These values seem very large.  The consensus seems to be that they should
    only be a few nano-secs.

4.  When one applies the CL table, the observed phase-vs-freq.
    slope of the visibility data (POSSM) doesn't change very much.
    I would think any kind of delay of micro-secs would scramble it
    (8.4 GHz data; 32MHz bandwidth)

Any enlightenments?  Also does anyone use TECOR for phase-referencing?
I do find that it makes a significant phase difference between the
reference and program sources, and thus would significantly affect
phase-ref. if the results are beleivable.  Any wisdom on which of the
jplg, esag, upcg or codg files to use?

   thanks,
