Phase picks on the USArray TA data are made by analysts at the Earthscope Array Network Facility (ANF). These ANF Event Bulletins are available as Searchable Product Depository (SPUD) products at the IRIS DMC or through the ANF website at Tools > Events. Once the final phase picks arrive at the IRIS DMC, they are sent to the International Seismological Centre (ISC) and are incorporated into the ISC Bulletins. As of November 2013, ANF Event Bulletins are complete through August 2013.
