Measured radial velocity is shown as a function of the modified Julian date (MJD) for five stars that display unusually large temporal variations in their measured velocities. The vertical extent of all five panels is ± 20 km s^-1 from the average radial velocity of the star (shown with a solid line). The dotted line indicates ±1.2 km s^-1, which is the average radial velocity σ for the entire RGB-GIRAFFE sample. Of these five stars only M244 has an average radial velocity consistent with membership of NGC 5927.
