rotation
a character vector. One of c("yaw1: clockwise",
"yaw2: clockwise","pitch1: nose down", "pitch2: nose down",
"roll1: starboard down","roll2: starboard down")
These data are raw bit values from a three-axis magnetometer and accelerometer. See the $rotation
column for
when each rotation starts and ends.
These data were recorded by Bill Hagey and Randall Davis.
