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.
