Pulsation model data for delta Cep and eta Aql

However, these classical implementations in general only use a subset of the available observational data. Freedman & Madore (2010ApJ...719..335F) suggested a more physical approach in the implementation of the parallax of pulsation in order to treat all available data.

We present a global and model-based parallax-of-pulsation method that enables including any type of observational data in a consistent model fit, the SpectroPhoto-Interferometric modeling of Pulsating Stars (SPIPS). We implemented a simple model consisting of a pulsating sphere with a varying effective temperature and a combination of atmospheric model grids to globally fit radial velocities, spectroscopic data, and interferometric angular diameters.
