    1212 * Gridded seismicity (or background) sources are composed of up to two Magnitude frequency distributions (MFDs) at each 0.1° x 0.1° spaced grid node. One is "associated" (as in small earthquake associated with any faults in a grid cell) and the other is "unassociated" (as in independent of any faults). These two MFDs must be added to obtain the total off-fault, gridded, or background seismicity source rate.

    14  * All rupture rates in a UCERF3 solution file are NOT declustered rates. All supra-seismogenic ruptures (those defined as finite faults) must be scaled by 3%. Gridded or background source rates must be scaled in a magnitude dependent manner according to the OpenSHA [http://source.usc.edu/svn/opensha/trunk/dev/scratch/UCERF3/utils/GardnerKnopoffAftershockFilter.java GardnerKnopoffAftershockFilter].

    16  * 3D finite representations of ruptures may be created from the individual fault sections defined in a solution file. For details on how to stitch the sections together in order see the OpenSHA implementation of a [http://source.usc.edu/svn/opensha/trunk/src/org/opensha/sha/faultSurface/CompoundSurface.java Compound Fault Surface].
