The following configuration options are available for this task:

# colormap for model/observations
colormapNameResult = blue-orange-div
# whether the colormap is indexed or continuous
colormapTypeResult = continuous
# color indices into colormapName for filled contours
# the type of norm used in the colormap
normTypeResult = symLog
# A dictionary with keywords for the norm
normArgsResult = {'linthresh': 30., 'linscale': 0.5, 'vmin': -100., 'vmax': 100.}
colorbarTicksResult = [-100.,-40., -20., -10., 0., 10., 20., 40., 100.]
# Adding contour lines to the figure
contourLevelsResult = np.arange(-100., 101.0, 10.)
contourThicknessResult = 0.5
contourColorResult = black
# Add arrows to contour lines
# whether to include arrows on the contour lines showing the direction of flow
arrowsOnContourResult = True
# colormap for differences
colormapNameDifference = cmo.balance
# whether the colormap is indexed or continuous
colormapTypeDifference = continuous
# the type of norm used in the colormap
normTypeDifference = linear
# A dictionary with keywords for the norm
normArgsDifference = {'vmin': -10., 'vmax': 10.}
# colorbarTicksDifference = numpy.linspace(-10., 10., 9)

# Months or seasons to plot (Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct,
# Nov, Dec, JFM, AMJ, JAS, OND, ANN)
seasons =  ['ANN']

# comparison grid(s) on which to plot analysis
comparisonGrids = ['latlon', 'subpolar_north_atlantic']

# list of tuples(pairs) of depths (min, max) to integrate horizontal transport over
depthRanges = [(0.0, -10000.0), (0.0, -2000.0)]

# minimum latitude (degrees) above which the mean BSF on boundary vertices
# averages to zero
minLatitudeForZeroBSF = -45.0

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.
