The 'standard plots' for ER040 are as follows:

  er040-weight.ps                station weight vs. time 
  er040-auto-[1,2].ps            station autocorrelation vs. freq
  er040-cross-[1,2][a,p].ps      baseline amp/phs vs. freq
  er040-ampphase-[a,p][2].ps     Ef-* baselines amp/phs vs. time

There were 2 different output multiple phase-center targets, but the
standard plots show visibility data from only the reference source and
fringe-finder, so only one set of standard plots is needed.
The auto and cross plots show data from scan 1 ([1], 1156+296) and
scan 131 ([2], OQ208, last fringe-finder while Sh still in the array). 

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
2s 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 the scans listed above.  Because of the RFI at
L-band, each IF for each station goes into a separately self-scaled plot
(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, using the same baseline lay-out on the page.
IFs per baseline are separated by the dashed vertical lines.
The polarization color-coding is RR=red, LL=blue, RL=cyan, LR=green. 
Phase(freq) plots show only parallel-hands for clarity.


(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 1s 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 plots.  The amp(t) plot
shows just the phase-reference source (including the fringe-finders would
dominate the vertical scale).  There is a second phase(t) plot that uses
integration number within the set of non-target scans each baseline has -- 
this essentially squeezes out the gaps and can give a better idea of the
phase behavior.
