Rotation curves and velocity dispersions of NGC 2523 and NGC 4245 derived from the velocities along each slit position. The filled diamonds represent data with errors less than 100 km s⁻¹. Error bars for rotation curve data points with errors greater than 100 km s⁻¹ are not shown for the sake of clarity. The xcor routine was unable to determine rotational velocities beyond approximately 59^{﹩\arcsec﹩} for NGC 2523 and 62^{﹩\arcsec﹩} for NGC 4245. The horizontal line corresponds to the inclination‐corrected maximum gaseous circular velocity of 294 km s⁻¹ for NGC 2523 and 199 km s⁻¹ for NGC 4245. These maximum gaseous circular velocities were derived from the works of Kamphuis et al. (1996) and García‐Barreto et al. (1994), respectively. The velocity dispersion values were corrected for an instrumental dispersion of 30 km s⁻¹. The xcor routine was unable to determine velocity dispersions beyond approximately 38^{﹩\arcsec﹩} for NGC 2523 and 55^{﹩\arcsec﹩} for NGC 4245.
