Fig. 3.


Smoothed velocity (left column) and velocity dispersion (right column) fields for the bright (top row) and faint (middle row) magnitude-corrected PN-samples. For comparison, the bottom row shows the smoothed fields for the total sample from Pulsoni et al. (2018). The solid grey lines denote the photometric major and minor axes of M49. The dashed lines divide the sample into four quadrants. The black cross denotes the position of the dwarf irregular galaxy VCC 1249. The mean errors on the smoothed fields are Δνbright = 39 km s−1, Δνfaint= 43 km s−1, Δσbright = 34 km s−1, Δσfaint = 38 km s−1 respectively. The bar in the lower-left corner of panel f corresponds to 25 kpc. North is up, east is to the left.
