Fetch frequency bands time history

GET /data/frequency/timehistory

Get noise frequency band time history for the selected instruments and time range.

Optionally choose which bands and weighting to use and what period to recalculate results to.

The maximum date range per request is 1 day. If you request a longer range, the server will respond with an error.
The default Period is 1 second.
The period can be set to anything between the current time history setting and 1 minute. If you request a period outside this range, the server will respond with an error.
You can request data with a period of less than 1 second by using a fractional seconds value in the period. For example, PT0.1S for 100ms.

Requires an API key with the data.noise:read scope.
