Site-wide coupling functions
============================

Summary plots can be generated for stations or entire sites with `pemcoupling-sitewide <../usage/basic.html#sitewide>`_.
A summary plot is generated by choosing the highest value at each frequncy bin across all channels at the desired station/site.
Measured values take precedence over upper limits.

Maximum coupling function
-------------------------

This shows the highest coupling at each frequency bin for all LHO magnetometers.
