Format

A 3002 x 6 data frame with column names attitude, timestamp, rotationRate, userAcceleration, gravity, and magneticField. The column names correspond to the measurements returned by a [CMDeviceMotion](https://developer.apple.com/documentation/coremotion/cmdevicemotion) object as described in Apple's developer documentation. rotationRate, userAcceleration,gravity are each 3002 x 3 data frames with column names x, y, z containing axial measurements for their respective sensor. magneticField has an additional column accuracy specifying the calibration accuracy of the magnetic field estimate. attitude columns are quaternion coefficients.
