The 'standard plots' for GF018B are as follows:

  gf018b-weight.ps                   station weight vs. time 
  gf018b-auto-[1,3].ps               station autocorrelation vs. freq
  gf018b-cross-[1,3][a,p].ps         baseline amp/phs vs. freq
  gf018b-ampphase-[a,p].ps           Ef-* baseline amp/phs vs. time

The auto and cross plots show data from the scans 92 [1], 208 [2] (both 3C84),
and scan 357 [3] (J0958+65; Br not in any fringe-finder scan).
The ampphase plots taken together show amp [a] or phase [p] vs. time for 
the whole experiment, omitting target scans. 

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
0.5s 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



(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 0.5s 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) plot shows only the main reference source J0958+65
to avoid the fringe-finders dominating the y-axis scale.
