The correlation for GG053C was done in two separate passes, one for each
of the two IFs.

The names of the plot files are:
  gg053c.IF[1,2]-weight-[1..4].ps.gz         station weight vs. time 
  gg053c.IF[1,2]-auto-[1,3,4].ps.gz          station auto-corr. real vs. freq
  gg053c.IF[1,2]-cross-[1,3,4][a,p].ps.gz    baseline amp/phs vs. freq
  gg053c.IF[1,2]-ampphase-[1..4][a,p].ps.gz  baseline amp&phs vs time

The plots vs time (weight, ampphase) collectively show the whole experiment;
    the number in [] refers to (approximate) quarters of the full experiment.
The plots vs. freq show 1min of data from a scan of J1241+602 ([1,4]) or
    a scan of J0927+3902 ([3]).
  In the baseline amp/phs vs freq plots, the 'a' or 'p' denotes an amp 
    or phase plot. 
The cover letter delves more deeply into the details of the specific plots.


(a) WEIGHT plots - plots each 0.25s integration as a separate ".".
The number in parentheses following each station is 0-based -- thus
one less that the corresponding station number in the AIPS FITS data.
Polarization color coding:  Red=LCP, Blue=RCP.


(b) AUTOCORRELATION SPECTRA plot - shows real vs. freq for each station.
The y-axis range in each plot self-scales independently, and  may not 
necessarily go down to 0.  
 

(c) BASELINE SPECTRA plot - shows (separately) amp and phase vs frequency
for all baselines, vector averaged in time over the annotated 1min interval.
The y-axis range in each amplitude plot self-scales independently.
Phase plots all show +/- 200 degrees.
     

(d) AMP/PHASE(t) plot - shows (separately) amp and phase on baselines 
EF-* (IF1) or Gb-* (IF2), over the whole experiment (but skips scans of 
the target source HDF).  Each 0.25s integration is plotted as a separate ".".  
The frequency points are vector averaged over the middle 80% of the band.
