cassini_mea_rcs_burns: A table containing information about main engine burns and thruster firings.  Most of the contents of this table were obtained from the JPL Navigation Wiki page for Maneuver Performance History. 

Column 1 has the Maneuver Names. Trajectory Correction Maneuvers (TCMs) were performed during Cassini’s cruise from Earth to Saturn. Saturn Orbit Insertion (SOI) was the maneuver that put the spacecraft into orbit around Saturn.  Orbit Trim Maneuvers (OTMs) were performed while in orbit around Saturn. 

The alphanumeric characters after the TCM and OTM designations indicate the specific maneuver.  Please note that for the Solstice Mission onward, the OTMs used standardized identification and were numbered to maintain a modulus 3 pattern.  Encounters with less than 3 planned maneuvers skipped OTM numbers and those with more than 3 had an alphanumeric character appended.  The skipped OTMs were OTM 293, 302, 305, 307 and 425.

Column 2 contains the Maneuver Description or Location.  For TCMs, the description shows maneuvers performed with respect to the following target bodies. 
	L=launch
	V=Venus
	E=Earth
	J=Jupiter
	S=Saturn
	Ph=Phoebe

V1 indicates the first Venus fly-by, and V2 denotes the second Venus fly-by.  The +/- values after the target body show the number of days maneuvers were performed after or before the target body.  For example, J-199d means that the maneuver was performed 199 days before Jupiter closest approach, and J+60d indicates that the maneuver occurred 60 days after Jupiter closest approach. 

For OTMs, the description shows the maneuvers for targeted fly-bys or for lowering/raising periapses during the end-of-mission phase.  
	T=Titan
	E=Enceladus
	H=Hyperion
	D=Dione
	R=Rhea
	I=Iapetus
	Per=Periapse

The alphanumeric characters after the body designation indicate the number of the targeted fly-by.  For example, Ta is the Titan-A fly-by.  D4 is the fourth Dione flyby. E19 is the nineteenth Enceladus fly-by.

Similar to Cruise, the +/- values after the target body show the number of days the maneuvers were performed after (clean-up maneuvers) or before the targeted fly-by.  T99+7d is the maneuver that was performed 7 days after the T-99 targeted fly-by. When ~per or ~apo was used, the maneuver was performed near periapse or near apoapse. 

The Maneuver Time shows the date (MM/DD/YY) and time (hh:mm) the maneuver was performed. Time is in UTC SCET (Universal Time Coordinated Spacecraft Event Time).

The Burn Time is the duration of the Main Engine burn or Thruster firing in seconds.  Burn Times were derived from telemetry and obtained from Todd Barber in the SpaceCraft Office (SCO).  The error in timing is approximately +/-250ms due mostly to on-board logic over-counting.  Attitude and Articulation Control (AACS) attempted to correct for the over-counting, but believe this small error may still exist.

The Burn Type is MEA for Main Engine Assembly (bipropellant) and RCS for Reaction Control System (thruster-based; monopropellant).  Cancelled, removed and contingency maneuvers that were not performed are shown in gray.
