The 'standard plots' for GP051D are as follows:

Line-pass plots: 

  gp051d-weight-[1-2].ps          station weight vs. time 
  gp051d-auto-[1-2].ps            station autocorrelation vs. freq
  gp051d-cross-[1-2][a,p].ps      Ef-* & Yy-* baseline amp/phs vs. freq 
  gp051d-ampphase-[1-2][a,p].ps   Ef-* baseline amp/phs vs. time

The plots vs. time are divided into 2 separate parts, each with about
2h20m 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 90 (3C84) 
and [2] scan 170 (3C84).  

Geod-pass plots:

  gp051d.geod-weight-[1-2].ps          station weight vs. time 
  gp051d.geod-auto-[1-2].ps            station autocorrelation vs. freq
  gp051d.geod-cross-[1-2][a,p].ps      Ef-* & Yy-* baseline amp/phs vs. freq 
  gp051d.geod-ampphase-[1-2][a,p].ps   Ef-* baseline amp/phs vs. time

Here, the two parts correspond to the beginning and ending geo-blocks
in the schedule.  The auto and cross plots show 1 minute of data from 
[1] scan 4 (2236+282) and [2] scan 174 (0808+495).  

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 (2s for the geod pass) as a separate ".".   
The IF/pol color-coding is for the line pass:  IF1/RR = red, IF1/LL = blue      
and the geod pass:  IF1/RR=red, IF1/LL=blue,  IF2/RR=cyan, IF2/LL=green


(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.  For the geod
plots, the IFs for each station are separted by the vertical dashed lines.  
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.  For the geod plots, the IFs per baseline are separated 
by the dashed vertical lines.  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 (2s for the geod pass) 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 plots.  
For each ~2h20m period of the line pass, 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
