@property<EOL><INDENT>def massrich_slope(self):<DEDENT>
return self._massrich_slope<EOL>
Slope of Mass-Richness relation:

        M200 = norm * (N200 / 20) ^ slope.

        Changes to massrich_slope will propagate to all mass-dependant
        variables. (This will take current n200 values and convert them to
        m200; in order to retain original values of m200, save them in a
        temporary variable and reset them after this change).

        :property: Returns slope
        :property type: float
            Default value is 1.4.
        :setter: Sets slope
