Pwear 3:00-4:00 bl
Description
Number of valid hours worn during free-living between 03:00-04:00; across the full data file (no sleep imputed / standard output). Non-wear periods are calculated as periods of time >=60 mins where the standard deviation of each of the three axes (x; y and z of the raw; triaxial accelerometry data) is <13mg. Both of these criteria are used to determine wear probability. This is the standard output (original) variable meaning no sleep imputation has been done. This variable indicates the total wear time between 03:00-04:00; across the whole data file; in hours. Baseline measure.
