Left: phase-space of PN candidates in the e²PN.S survey footprint, including PNe associated with M 105 and NGC 3384. The major axis of M 105 is denoted with x_M 105. Right: line-of-sight velocity histogram of the objects shown in the left panel. The dashed line denotes the systemic velocity of M 105, and the solid blue line the mean velocity of the sample. The blue shaded regions denote the 1, 2, and 3σ intervals from the mean. Objects beyond 3σ of the mean velocity are likely redshifted background emission-line galaxies.
