This is a modification of gmsim_v16.1 based on the work of Robin Lee in 2017/2018. This version implements a single change:
Removing the long period site amplification (or reducing to a 1-2s taper as opposed to the previous 2-5s taper?)
This change to reduce the long period site amplification was as a result of the CB14 site amplification overamplifying long periods since it double counts for velocity features which are already explicitly modelled in the LF simulations (due to the high resolution 3DVM).

The computational implementation of this modification is to change the "fmin" and "fmidbot" variables in the params.py file:
e.g.
site_fmin = '0.5'
site_fmidbot = '1.0'
