  A subset of Post-AGB (PAGB) objects are the highly luminous RV Tauri
variables that show similarities to Type-II Cepheids. By using a sample of
known RV Tauri stars from the Magellanic Clouds we are able to determine period
luminosity relationships (PLRs) in various bands that have been used to
determine the luminosities of their Galactic counterparts. We have gathered all
available photometry in order to generate an SED for each object and determine
the total integrated flux. This total flux combined with a calculated or
inferred intrinsic luminosity leads to a distance (Vickers et al. 2015). This
distance catalogue has allowed us to begin to constrain the physical parameters
of this poorly understood evolutionary phase and to determine links between
these physical characteristics as a function of their stellar population.
