Events extended csv

Column HeadingDescription
Sample Time Date and time encoded as a floating point number, The integer part of number represents the date. The decimal portion represents the time.

To view the time in Excel, follow this these instructions
Time (approx)For convenience, the date and time accurate to the nearest second. This should not be used for calculations of time diffferences
Data CountCount in 0.1s resolution from the start of the recording
Event TypeThe event type:
0 – sedentary
1 – standing
2 – stepping
(Note: step events are single legged steps, and must be doubled to calculate stepping totals)

With the latest classification algorithm, additional event types are available:
2.1 – cycling
3.1 – primary lying
3.2 – secondary lying
4 – non-wear
5 – seated transport
DurationThe duration of the event in seconds
Waking Day0 – events during identified primary time in bed period
1 – events during identified waking day
Valid Day0 – event is part of validation algorithm identified invalid day
1 – event is part of validation algorithm identified valid day
Locus1 – event is part of algorithm defined primary locus
2 – event is part of algorithm defined secondary locus
3 – event is part of algorithm locus transition
Cumulative Step CountCumulative total of all stepping events
Activity ScoreActivity score in MET.h for each event
AbsSumDiffXSum of the absolute sample to sample differences on the x axis
AbsSumDiffYSum of the absolute sample to sample differences on the y axis
AbsSumDiffZSum of the absolute sample to sample differences on the z axis
Time UprightTime in upright orientation during the event
Time Upside DownTime in upside down orientation during the event
Time Back LyingTime in back lying orientation during the event
Time Front LyingTime in front lying orientation during the event
Time Left LyingTime in left lying orientation during the event
Time Right LyingTime in right lying orientation during the event

In addition, aP4+ recordings provide the following outputs:

Column HeadingDescription
Heading (degrees)The per-step average heading in degrees
Heading Change (degrees)The heading change from the previous step in degrees. This is for convenience as it takes into account the discontinuity crossing from 0 to 360 degrees
Heading QualityPercentage heading quality index to indicate calibration errors
Height Change (m)Change in altimeter height from the previous step
