Abstract: By phasing using the minimum of the acceleration curve of a selection of Type II Cepheids of a range of periods, a clearer understanding of the pulsational dynamics of the stars us obtained. BVRI photometry and a selection of metallic line velocities and Hα equivalent widths are presented using this phasing.
