# Site-wide coupling functions¶

Summary plots can be generated for stations or entire sites with pemcoupling-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.

## Maximum estimated ambient¶

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