When creating mseed files:
Uses the TauPy iasp91 global model for estimating arrival time
Questions to be answered:
1) Do we want to do the SNR steps for accepting or ignoring records?
2) If we want to do SNR, do we care about the phase arrival time selection being from the old method (from the FDSN_Client)
3) Do we care about how if records are removed from this filtering that they won't appear in the flatfile at the end when merged with the final dataset from IM_calc etc
Values affected if we remove SNR from the flatfiles
If there is no epicentral distanc emeasured then there will be no differnce
I there is a measurement and SNR passes then these columns will change values

columns=[
"mag_corr",
"mag_corr_method",
"amp",
"amp_peak",
"amp_trough",
"amp_max",
"amp_unit",
"SNR",
"filtered",
"amp_time",
] |
All of these columns are None for other accepted record paths, except for the ones listed below
1 - mag_corr_method - "uncorrected" in all other cases
2 - amp - Taken from the generic amplitude from the event catalogue
3 - amp_unit - Taken from the amplitude unit from the event catalogue
When SNR is taken into account amp is calculated based on the trace data and the amp unit is always "mm"
Extra questions
What values do we actually use from the flatfiles? (Is there some columns we could ignore and remove unneeded compute for)

Extra notes
- station_magnitude csv is duplicated with the mags csv?
- Not every record has SNR
