==================================== ============== =============
Name Units Description
==================================== ============== =============
maxmagnitude m/s\ :sup:`2` The maximum magnitude of acceleration (:math:`\|acceleration\| = \sqrt{x^2 + y^2 + z^2}`).
minmagnitude m/s\ :sup:`2` The minimum magnitude of acceleration.
avgmagnitude m/s\ :sup:`2` The average magnitude of acceleration.
medianmagnitude m/s\ :sup:`2` The median magnitude of acceleration.
stdmagnitude m/s\ :sup:`2` The standard deviation of acceleration.
ratioexertionalactivityepisodes The ratio of exertional activity time periods to total time periods.
sumexertionalactivityepisodes minutes Total duration of all exertional activity episodes during ``day_segment``.
longestexertionalactivityepisode minutes Duration of the longest exertional activity episode during ``day_segment``.
