csep.core.catalogs.CSEPCatalog.spatial_magnitude_counts
- CSEPCatalog.spatial_magnitude_counts(mag_bins=None, tol=None)
Return counts of events in space-magnitude bins.
It figures out the index of the polygons and maps the spatial coordinates in the Cartesian grid with the polygon in region.
- Parameters:
mag_bins (array-like) – magnitude bin edges (optional), by default uses magnitude bin edges associated with region.
tol (float) – overwrite numerical tolerance, by default determined automatically from the magnitudes’ dtype to account for the limited precision of floating-point values. Only necessary to specify if the magnitudes were subject to some floating-point operations after loading or generating them (increased roundoff error, see
csep.utils.calc.bin1d_vec()).
- Returns:
- unnormalized event count in each space-magnitude bin (2d, with indices
corresponding to spatial midpoints and magnitude bin, respectively)
- Return type:
