The AC6 dataset is provided in 4 ASCII files each day. Survey files contain 1 Hz dosimeter data an minimal ephemeris. Coordinates file contain extended magnetic coordinates at 1 Hz. Attitude files provide detailed attitude information at 1 Hz. 10 Hz files provide the high resolution data taken in burst mode. The data dictionary indicates which quantities are in which file.
