missionbay_calib2: Magnetometer/accelerometer calibration data.
Description
Empirical magnetometer/accelerometer calibration data from Mission Bay, CA. These data are a sequence of 2 clockwise yaw rotations, 2
pitch rotations (nose down), and 2 roll rotations (nose facing west, starboard down).
Usage

These data were recorded by Bill Hagey and Randall Davis.Details
These data are raw bit values from a three-axis magnetometer and accelerometer. See the $rotation column for
when each rotation starts and ends.
