This is the Earthworm hypocenter garbage rejector. EqfilterII is an expansion of eqfilter and fully backward compatible to config files designed for eqfilter. EqfilterII gets message types LOC_GLOBAL, HYP2000ARC, and/or RAYLOC from the InRing does some sanity checks then puts any that pass all configured tests onto the OutRing. InRing and OutRing can not be the same. Multiple message types may be configured for a single instance of eqfilterII. All tests are optional. Some tests are specific to a particular message type and will be ignored if a differing message type is processed. If a test is not configured then it is not performed. If a test is configured then it must pass. Most parameters in the various message types may be tested. Tests are tied to inst_id (wild cards okay). Additionally, authoritative regions may be configured. Minimum number of coda picks greater than zero for multiple magnitudes may also be configured.
INST_WILDCARD is allowed. If wildcard is the only installation configured for a given test then arc messages from all installations will be tested with those parameters. If only a specific installation is configured for a given test, then only messages from that installation will be tested and all others will fail. If a specific installation is configured for a given test and wildcard is also configured for that test, then messages from the specific will use those parameters, and all other non-specified installations will use the wildcard params.
