 By default, the BSF is computed over two depth ranges---the full depth of
 the ocean and only to 2000 m.  By default, global and subpolar North Atlantic
 plots are produced.  The BSF is constrained to have a mean value on coastal
-boundaries of zero north of ``minLatitudeForZeroBSF``.
+boundaries between the bounds set in ``latitudeRangeForZeroBSF``.

+You can set config options for individual comparison grids in a separate
+seciton with the suffix associated with the comparison grid appended, e.g.::

+
+You must define both a new set of colormaps, norms, etc. and a new range of
+latitudes over which the BSF is constrained to have a mean value of zero.
+
+This is useful because plots are more intuitive if the BSF is close to zero
+at local boundaries.
