Notes on processing each day and campaign are in the dated
subdirectories.  Each subdir, even if all days are run as a single
survey, has a further subdir for a day, where the actual output is
kept.  This is to ease scripting a reduce_all command that will rerun
all the data.  It also keeps any campaign from being a special case.

The August and Sept campaigns are the best from a drift standpoint,
with near-zero drift during the surveys - 30 uGal over 2+ days!

Looking over Winester's report for absolute gravity, there is no
significant change at Morrill or SBNM; so can use either as stable.
Morrill has more measurements, so redo analysis with Morrill stable for
all surveys.

Build "reduce_all" shell script to redo all analyses at once; puts
output into "reduceOutput" here, and "out" in each subdir.  Filter for
directories is "*/*/reduce.cmd".

Rerun make_table to create new relative table.  Edit "make_table" to
automatically generate postscript with 4-pt font for viewing without
line wraps.

Create "makeMatlab" to create [07, 08, 09, 10].plt files for plotting
in Matlab.  Uses UTM coordinates converted from stations.coords and
stored in stations.utm, via program name2coord.py.

Make contour plots in Matlab using plotMaps.m; creates 4 figures: 1 for
Jul-Jul, Aug-Jul, Sep-Jul, and Oct-Jul.  Colorbars are in mGal.
Contours are from cubic gridding of stations on 50x255 grid (X x Y).

SUMMARY OF PROCESSING PIPELINE (data files to maps)
------------------------------
./reduce_all
./make_table
./makeMatlab
matlab
  plotMaps

Interpretation
--------------
Inspection of Aug, Sep, and Oct changes indicates the project mostly
seems to have worked.... Changes in Aug centered around northern line
of wells and 1F, which are next to the canals.  Changes in September
are smaller than Aug, but still mostly positive.  Changes in October
show large drops in north, with only positive buildup still occuring in
south along the southern canal.

How does this compare to well data?
