On the Extraction of Optical Rotation Curves for Spiral Galaxies
We discussed four different methods - the single, double and triple Gaussian fits, and the intensity weighted centroid fit - which extract rotation curves from several emission lines ([OII], Hβ, [OIII], and Hα) of spiral galaxies. Spatial extents and the shapes of rotation curves derived through var...
