Explanation of the columns:
#: name of the maneuver;
Burn time: starting UTC burn time;
DV: difference between the inertial velocity vector 1 ms before the burn and the inertial velocity vector 1 ms after the burn (mm/s);
Dt: burn duration (s);
a: average acceleration during the burn (mm/s
2, simply a = DV / Dt).
All the values are calculated from the NAIF's data files by means of the SPICE library.
Spacecraft axes:
some graphs show the spacecraft orientation according to the figure. Official website page:
Spacecraft Coordinate System.
The graphs use the following color convention: the red line is aligned with the +Z axis (during a burn, it represents the direction of the thrust vector when the main engines are used, in other words the propellant is ejected from the main engines in the -Z direction); the blue line is aligned with the +X axis and represents the
HGA boresight; the green line is aligned with the +Y axis.
