Data

115,464 bulk items are available, covering 103,688 participants.
Defined-instances run from 0 to 4, labelled using Instancing 93.

Detailed summary is not currently available.

Notes

These files contain the raw acceleration data, per participant, from a single use (over a 7-day period) of the physical activity monitor. Format is native cwa as returned by the device.

Files are typically 250MB each in the raw state and usually compress to around 100MB.
