Acceleration profiles and processing methods for parabolic flight

Parabolic flight acceleration data and analysis methodology. a Typical flight path during a single parabola. b Research section of aircraft with baseplate location during flight. c Accelerometer orientation on baseplate. d Overview of analysis method. e Measured accelerations after low-pass filtering (gfilt). f Change points (vertical lines) for mean g levels as measured by gfilt. g–i Second-level linear change points (vertical dotted lines) define transition regions for a Mars, a lunar, and a 0？g parabola, respectively. Individual parabolas corresponding to g–i are labeled in f. For accelerations during each of the 20 parabolas, see Supplementary Figs. 6–
