GRRateGrid

Subclass of pandas.DataFrame, storing the Gutenberg-Richter rate values for a spatial grid. Holds additional methods to work with this data structure.

Constructor

GRRateGrid	Represents seismicity as a grid of cells, each with its own Gutenberg-Richter parameters (a-value, b-value, and mc).
GRRateGrid.concat	Concatenate a list of GRRateGrid objects into a single GRRateGrid with a MultiIndex using starttime, optionally endtime and a unique cell number.

Modify GRRateGrid

GRRateGrid.strip	Remove all columns except the required ones for a GRRateGrid.
GRRateGrid.add_time_index	Create MultiIndex using starttime and endtime, both taken from the object attributes, and a cell number for each spatial block.
