Partition number

The measurements of a session were subdivided into sub-periods or partitions. These partitions were defined by a series of location changes recorded on the sessions log sheet. Each continuous period in a location is considered to be a separate partition.

ATTRIBUTE-ACCURACY

The start and stop times of the partitions are considered to be accurate within a couple of minutes.

DOMAIN

The partitions are numbered chronologically. Any measurements prior to the first location record are part of partition number zero. Partitions starting with the first location record are numbered from one. Any measurements following the conclusion of the 24-hour period considered in this study are considered part of a single partition and are numbered as other partitions.
