The radial velocities of the ionized gas in the double system of galaxies NGC 2535-36 (Alp, 1982) have been measured with a scanning -Fabry interferometer and a two-dimensional photon counting system (the CIGALE equipment). Some 3200 velocity points cover the whole galaxy and its companion with a spatial resolution of 1.5" and a velocity accuracy better than 19 km s-1. The redshifts are found to be 4095 km s-1 ± 10 km s-1 for NGC 2535 and 4085 km-1 ± 10 km s-1 for NGC 2536 (heliocentric radial velocities). Assuming a distance of 41 Mpc the masses are found to be around 3 × 1010 Msun for the main galaxy and 2.7 × 109 Msun for its companion. The interaction is in a quite advanced state, as suggested by the perturbations seen in the velocity field of both galaxies.
