We do this by manually downloading CSV data and converting it to Seiscomp SCXML, then importing it into our server to be accessed via FDSN as event data. Because we must do this manually, our cloned earthquake catalog is only updated monthly (usually on the 1st). Note that information such as phase arrivals is unfortunately not provided by GA.

EarthScope's solution was to add a -1 multiplier to the //response data.// Because we have a much smaller volume of this data to fix, and far less of it already distributed prior to this announcement, we have opted to do the opposite; e.g. we invert the //raw data// because the data is what is wrong; not the response.
