Because there was no scan in which all 17 stations participated at the same
time, the normal automatic standard plots didn't provide a complete overview
of the experiment.  I therefore made some manual plots that provide similar
information to allow a review of the correlation.  The combination of all
plots shows all stations at least once for each type of plot.

The names of the plot files are:

  gi001b.[RUN]-weight.ps.gz               station weight vs. time  (full exp)
  gi001b.[RUN]-auto-[SCAN].ps.gz          station autocorrelation real vs. freq
  gi001b.[RUN]-cross-[SCAN][a|p].ps.gz    baseline amp/phs vs. freq
  gi001b.[RUN]-ampphase-[STA][a|p].ps.gz  baseline amp/phs vs time

[RUN] is one of "cont", "lineL", or "lineR".  Each polarization for the 
  line correlation filled the correlator, so had to be run separately.

[SCAN] for the plots vs. frequency refers to the scan used for the plot.
   32 = 1830+139,  04:24-35,  ref.sta = EF
  124 = OT081,     10:02-07,  ref.sta = PT
Each of the plots uses 2 minutes of data from the scan, ending ~30s prior 
to the end of the scan.

[STA] for ampphase plots (vs. t) refers to the reference station used for 
the plot.
  EF = Efflesberg - shows all baselines Ef-* for as long as Ef was in the array
  PT = Pie Town - shows baselines Pt-VLBAs for as long as Pt was in the array

[a|p] for amp/phs plots refers to amp (a) or phase (p).



(a) WEIGHT plot -  shows all IF/pols, with color-coding

   cont:  Red = IF1/LCP  Blue = IF1/RCP  Cyan = IF2/LCP  Green = IF2/RCP
                    Magenta = IF3/LCP  Yellow = IF3/RCP
   lineL:  Red = IF1/LCP
   lineR:  Red = IF1/RCP

Each integration is plotted as a separate ".".
Note that since the continuum run was performed by commenting out IF1 in 
the VEX file, the correlator viewed this as a 3-IF run, and the scheduled 
IF numbers (2,3,4) were labelled (1,2,3) in the subsequent stages of
the data (measurement set, FITS files).  Thus IF1 in the continuum part
does not correspond to IF1 in the line part.


(b) AUTOCORRELATION SPECTRA plots - The y-axes may not necessarily go down to 0.
All IFs plotted to same y-axis scale.  RFI seen in upper two continuum IFs is
not at all constant in time.  Color coding (per IF):  Red = LCP, Blue = RCP.
 

(c) BASELINE SPECTRA plots - show (separately) amp and phase vs frequency
for baselines to the reference station, vector averaged in time (time-range 
in lower-right corner).  Color coding is the same as for autocorrelation plots.
The y-axis ranges self-scale, not necessarily going down to 0 for amp, nor
encompassing a full 360deg for phase.
     

(d) AMP/PHASE(t) plots - show all IFs/pols for baselines to the reference
station, but not including data from the targets.  Color coding is the same
as for the weight plots.  The frequency points are vector averaged over the
middle 80% of the band to make these plots.  Each integration is plotted as
a separate ".".
