Abstract

A probabilistic approach has been used in combination with the parallax data from Gaia (e)DR3 to calibrate Period-Luminosity-(Abundance) (PLZ) Relations covering a wide range of visual to Infrared observations of RR Lyrae stars. Absolute Magnitude Relations are given, derived from the same selection of stars, for V, G, I, K_s and WISE W1 as well as for for the reddening free pseudo-magnitudes WBV, WVI and finally also Gaia WG. The classical relation between M_V and [Fe/H] is redetermined and as an illustration distances are given to a few selected objects.
