The 'standard plots' for GF015A are as follows:

  gf015a.Q[i][c]-weight.ps              station weight vs. time 
  gf015a.Q[i][c]-auto.ps                station autocorrelation amp vs. freq
  gf015a.Q[i][c]-cross-[a,p].ps         baseline amp/phs vs. freq
  gf015a.Q[i][c]-ampphase-[a,p].ps      Ef-* baseline amp/phs vs. time

The field "Q[i][c]" represents a portion of the experiment from which
the data in the plot are taken (i=1,2,...6; c='a','b','c','d').  The
scan-ranges of these parts are:
   1a =  1-15     3a = 115-129     5a = 203-214 
   1b = 16-30     3b = 130-144     5b = 215-226
   1c = 31-44     4a = 145-159     5c = 227-238
   1d = 45-58     4b = 160-174     5d = 239-249
   2a = 59-72     4c = 175-188     6a = 250-263
   2b = 73-86     4d = 189-202     6b = 264-277
   2c = 87-100                     6c = 278-291
   2d =101-114
The auto and cross plots show 1min of data taken from the fringe-finder
scans, and thus have only 4 Q[i][c] parts (Q1b = 3C84, scan 28; 
Q2c = J0927, scan 88; Q3b = J0927, scan 144; Q6a = 3C84, scan 252).
The cross & ampphase plots show amp [a] or phase [p] in separate plots.

The antenna numbering in these plots is 0-based -- thus one less than the
corresponding antenna numbers in the AIPS FITS file.  Further comments about
the plots can be found in the PI-letter.


(a) WEIGHT plots

  The plot shows the weights for all IFs (parallel-hands only) per station,
with each 0.25s integration plotted as a separate ".".   The IF/pol 
color-coding is:

 IF1/RR = red    IF1/LL = blue      IF2/RR = cyan        IF2/LL = green
 IF3/RR = pink   IF3/LL = med.grey  IF4/RR = brown       IF4/LL = purple
 IF5/RR = teal   IF5/LL = yellow    IF6/RR = steel blue  IF6/LL = lt.grey
 IF7/RR = black  IF7/LL = orange    IF8/RR = lt.green    IF8/LL = lt.purple


(b) AUTOCORRELATION SPECTRA plots

  The plots show 1min of data from the fringe-finder scans listed above.
All IFs for a station share the same plot, separated by the dotted
vertical lines.  Each station's plot self-scales; the y-axis range doesn't
necessarily go down to zero.  The polarization color-coding is: red=RCP,
blue=LCP.  The plots show the real component rather than amplitude to
avoid aliasing negative values.  


(c) BASELINE SPECTRA plots 

  The baseline vs. frequency plots show amplitude and phase for all
baselines for the same 1-minute intervals as the autocorrelation plots.
Amp(frq) and phs(frq) go into separate plots with corresponding lay-out
of baselines over the (up to) 4 pages.  All IFs for a baseline share the
same plot, separated by the dotted vertical lines.   The amplitude plots
self-scale per baseline; the phase plots have a fixed y-axis range
(+/-200deg).  Polarization color-coding within each IF is red=RR, blue=LL.


(d) AMP/PHASE(t) plots 

  The Ef-* baseline vs. time plots show amp and phase in separate plots.
These plots show only non-target scans within each part of the experiment.
Each 0.25s integration is plotted as a separate ".", with the middle 80% of
the band used for vector-averaging over frequency.  The IF/pol color-coding
in the amp(t) plot is the same as for the weight plot.  The phase(t) plot
shows only IF2-3, where the Da signal is -- the color-coding here changes
to:  IF3/RR = red   IF3/LL = blue   IF4/RR = cyan  IF4/LL = green.
