public abstract class MagAreaRelationship
extends MagScalingRelationship

Title:MagAreaRelationship
Description: This is an abstract class that gives the median and standard deviation of magnitude as a function of area (km-squared) or visa versa. The values can also be a function of rake. Note that the standard deviation for area as a function of mag is given for natural-log(area) not area.
