Correct indexing of mMax models for CEUS gridded sources #61

Closed pmpowers-usgs closed 7 years ago

pmpowers-usgs commented 7 years ago

MFDs for CEUS gridded sites are computed using a total MFD across all mMax models and then applying a mask, which scales the upper magnitudes to their appropriate rates. The mask indexing is currently off-by-one; e.g. for an mMax of 7.2, the uppermost magnitude bin will be 7.15 such that the mask should be applied at 7.25, but it is not applied until 7.35.
