Here are the 12 impulsive micro-maneuvers performed during the Orbital R phase (obtained from the NAIF's data file updated with tracking data through 13-JAN-2020 17:33:57).
The column "DV" shows the variation of the inertial orbital velocity expressed in µm/s. For comparison, consider that the largest of the maneuvers (#6) is about 220 times smaller than the average orbital speed.
The graph shows the position and the orientation of the s/c in the Bennu-centric Sun-North reference frame. For the sake of clarity, the spacecraft Y axis is not shown.

Black dots: s/c position. The popup label shows the UTC time and the inertial orbital speed (mm/s). Red diamond: s/c position at the time of the impulsive burn. Red lines: spacecraft +Z axis. Blu lines: spacecraft +X axis.
Here are the orbits from October 31 to January 13 in the Bennu-centric Sun-North reference frame.
The graph also shows the spacecraft orientation during the M13R maneuver.
The popup label shows the date, the radius vector (m), the altitude above Bennu (m) and the spacecraft orbital speed (mm/s).
Here's the same graph as above, but in the mean ecliptic and equinox of J2000 reference frame.
