^a Red and Blue shifted emission are calculated by subtracting the central part of the line profile with a Gaussian with FWHM of 1.5-2 km s^-1.
^b Position: $\Delta$ RA = -20'', $\Delta$ Dec = -20''.
^c Velocity range used for integration: -5 km s^-1 to 15 km s^-1
^d Upper limit of 3 $\sigma$ in a 0.7 km s^-1 channel.
