We evaluated the availability of a method proposed by Kuno et al. (2000, PASJ, 52, 775) for measuring the pattern speed of barred galaxies, and applied it to observational data. We made error estimations using a hydrodynamical galaxy model to test the validity of the method. Error estimations suggest that the method is able to determine the pattern speed within an error of 10%–20%. The method was ...
