Spoiler

@sevenperforce, 17D15 maneuver thruster, syntin-gaseous O2 bipropellant, 4 kN thrust, 275-295 sec ISP (top value for prograde thrusters with extended nozzles), up to 2000 pulses of 0.06-1200 sec at 8 Hz with 90% nominal thrust achieved in 0.06 sec; electric inductive ignition, mixed regenerative-radiative cooling.

Vernier RCS - 200 N, 265 sec ISP, 5000 pulses of 0.06 to 0.12 sec, with an oxidizer-rich mixture ratio of 3.5-4.

Inductive ignition is nice but catalytic ignition is faster and more reliable. Though H2O2 is not terribly pleasant to handle.
