**use_amplitude** parameter guidance #45

Closed iqram1337 closed 1 week ago

iqram1337 commented 9 months ago

  1. Why i can't turn on use_amplitude parameter with chile region in example notebook?

  2. In the other hand, i have tried using 1 event with 6 stations (3 components), but when I compare it with the original event information, the magnitude of the gamma generated is 8 (always 8 even if the dbscan parameter is changed repeatedly), whereas it should be 3.5. When i turn off turn use_amplitude the gamma standard_catalog return nothing, 0 event

Hi,

  1. the chile example does not have "phase_amplitude" in the phase file.
  2. Can you check your phase_amplitude (in PGV, m/s) is normal?

how to check the units? i honestly no idea what the unit is. The amplitude is just straight output from the PhaseNet. Please help me with this. thank you
