Wrong unit for the eventid queries #14

Closed krischer closed 8 years ago

krischer commented 8 years ago

The eventid queries don't convert the moment tensor components from dyne*cm to Nm. Thus the amplitudes are way off when using the eventid parameter. Just multiply with 1E-7 to fix that issue.
