The 'standard plots' for GF018A are as follows:

  gf018a-weight-[1,2].ps               station weight vs. time 
  gf018a-auto-[1,2].ps                 station autocorrelation vs. freq
  gf018a-cross-[1,2][a,p].ps           baseline amp/phs vs. freq
  gf018a-ampphase-[1,2][a,p].ps        Ef-* baseline amp/phs vs. time

The auto and cross plots show data from the scans 48 [1] and 312 [2] 
(both 3C84).  The plots vs. time are split into halves of the experiment
as denoted by the [1,2].  The ampphase plots taken together show amp [a]
and phase [p], omitting target scans.  There are two further phase(t)
plots as described below.

The antenna numbering in these plots is 0-based -- thus one less than the
corresponding antenna numbers in the AIPS FITS file.


(a) WEIGHT plots

  The plots shows the weights for all IFs/pols 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 data from 1 minute of the scans listed above.  The IFs 
for each station go into plots along a row separated by the vertical
dashed lines.  Since each row self-scales, their y-axes may not go down 
to zero.  The polarization color-coding is RR=red, LL=blue. 


(c) BASELINE SPECTRA plots 

  The baseline vs. frequency plots show vector-averaged amplitude and phase 
for all baselines for same the time ranges as the autocorrelation plots, with
amp & phase going to separate plots using the same baseline lay-out on the 
page.  The polarization color-coding remains RR=red, LL=blue. 


(d) AMP/PHASE(t) plots 

  The baseline vs. time plots show amplitude and phase for non-target scans, 
with amp & phase going to separate plots.  Each 0.25s integration is plotted
as a separate ".", with the middle 80% of the band used for vector-averaging
over frequency.  The plots use the same IF/pol color-coding as in the 
weight plot.  The amp(t) plots shows only the main reference source J0958+65
to avoid the fringe-finders dominating the y-axis scale.
The phs(t) plots only a subset of IFs/pols: IF1-6,8/RR.  This avoids 
places where individual stations have problems (Sv LCP, Br IF7) that
would mask the patterns in the phs(t) plots.
There are two additional phs(t) plots to illustrate the behavior of Jb1:
    gf018a-ampphase-3p.ps - scan 48, phs(t) on baselines in JbWbEf,
       same IF/pol color-coding
    gf018a-ampphase-4p.ps - scan 48, phs(t) on Jb-Ef with IFs plotted
       separately,  RR=red, LL=blue
