Quick and dirty real time HVSR monitor because it wasnt an option in swarm.
Change the relevant python path at the top.
Run from the command line as;
./real_time_HVSR.py $station $channel_prefix
where channel prefix is likely "HH", e.g.
./real_time_HVSR.py ERZ1 HH
I'll make this more elegant next week - or feel free to!
