	CTC Software is designed to input EEW trigger information and produce performance summaries. It is designed to support EEW triggers in multiple formats and is intended support processing of ShakeAlert EEW trigger files. Currently two trigger types can be processed, Virtual Seismologist lead by Swiss Seismological Service at ETH Zurich, and On Site lead by Caltech seismology lab. Support for UC Berkeley ELarms and CISN ShakeAlert are planned.		CTC Software is designed to input EEW trigger information and produce performance summaries.

 Next, the event arrived by email but was not available in the ANSS catalog. We had to manually enter the event information from the email into an anss catalog entry for use in processing.
 Then we saw that all the stations in the ShakeMap observation file were NorCal stations, however the forecast stations in the VS trigger were all southern California stations. This looks to be a limitation of using ShakeMap files for source of observational data
