The 'standard plots' for GP051B are as follows:

  gp051b-weight-[1-3].ps          station weight vs. time 
  gp051b-auto-[1-3].ps            station autocorrelation vs. freq
  gp051b-cross-[1-3][a,p].ps      Ef-* & Yy-* baseline amp/phs vs. freq 
  gp051b-ampphase-[1-3][a,p].ps   Ef-* baseline amp/phs vs. time

The plots vs. time are divided into 3 separate parts, each with about
2 hours of data.  The ampphase plots show amp [a] and phase [p] separately;
there are two variants of the amp(t) plots, as described in more detail below.
The auto and cross plots show 1 minute of data from [1] scan 3 (3C454.3),
[2) scan 91 (3C84), and [3] scan 181 (3C84).  

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
0.35s integration plotted as a separate ".".   The IF/pol color-coding 
is: IF1/RR = red, IF1/LL = blue      


(b) AUTOCORRELATION SPECTRA plots

  The plots show data from the scans listed above.  Since the plots for
each station self-scale, 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
with amp & phase going to separate plots denoted by the 'a' or 'p' following
the scan identifier.  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, denoted by the 'a' or 'p' following
'ampphase-'.  Each 0.35s integration is plotted as a separate ".", with the
middle 80% of the band used for vector-averaging over frequency.  The
color-coding remains the same as in the weight plot.  For each ~2hr period,
there are two amp(t) plots (-{N}a, -{N}a2) and one phase(t) plot (-{N}p),
where {N} = 1,2,3, such that:
  -{N}a:  amp(t) for only J0038+4137 scans (to avoid the fringe-finders
         from dominating the y-axis scale
  -{N}a2: amp(t) for all non-target scans
  -{N}p:  phase(t) for all non-target scans
