Description

I want to make the green's functions for 1D local velocity model with these parameters:
freqmin = 0.025
freqmax = 1.0
npts = int(2048)
dt = 0.02
The synthetics have been generated. But it is difficult to match the waveforms. The output parameters looks like this.

Deviatoric Moment Tensor Inversion
Depth = 5.0000 km
Mw = -0.42
Percent DC/CLVD/ISO = 28/72/0
VR = 0.00%

Deviatoric Moment Tensor Inversion
Depth = 15.0000 km
Mw = -0.25
Percent DC/CLVD/ISO = 79/21/0
VR = 0.01%

Additionally, I have attached the waveform fits. Please inform me if any errors are present in my approach.

Research direction

No repository files, tests, or entry points are named. Start by reproducing the 1D local velocity-model run with the stated frequency, sample-count, and time-step parameters, then compare the generated synthetics with the observed waveform fits and document the cause of the mismatch.
