The correlation for GG060 was done in four separate passes, resulting
from the combinations of:
   2 phase centers  (M81, M82)
 & 2 polarizations  (LCP, RCP)


The names of the plot files are:
     gg060.[WHAT]-weight-[1...4].ps.gz  station weight vs. time 
     gg060.[WHAT]-auto-2.ps.gz          station autocorrelation real vs. freq
     gg060.[WHAT]-cross-2[a|p].ps.gz    baseline amp/phs vs. freq
     gg060.[WHAT]-ampphase-2.ps.gz      baseline amp&phs vs time
[WHAT] refers to the correlation pass: m81l = M81,LCP;  m81r = M81,RCP;
   m82l = M82,LCP;  m82r = M82,RCP

The weight plots collectively show the whole experiment; the number in []
    refers to (approximate) quarters of the full experiment.
The plots vs. freq show 2min of data from the fringe-finder (3C84) scan 
    (the only fringe-finder was in the second quarter of the experiment).
    In the baseline amp/phs vs freq plots, the 'a' or 'p' denotes an amp 
    or phase plot.
The ampphase plot shows ~1.5hr around the time of the 3C84 scan.
More about specific details from these plots in the cover letter.


(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.


(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 2min of the fringe-finder
3C84.  The y-axis range in each amplitude plot self-scales independently.
Phase plots all show +/- 200 degrees.
     

(d) AMP/PHASE(t) plot - shows Pt-*, in the time range around 3C84.
Color-coding is by source (blue=3C84, green=J0958+6533, red=M81).
Pt was selected as the reference station to maximize the number
of short baselines plotted.  The frequency points are vector averaged
over the middle 80% of the band. 
  M82L,R use La as the reference station rather than Pt, since Pt had
worse playback in the 3C84 scan for that run.
