We present a theoretical calibration of the RR Lyrae period-luminosity (PL) relation in the UBVRIJHK Johnson-Cousins-Glass system. Our theoretical work is based on calculations of synthetic horizontal branches (HBs) for several different metallicities, fully taking into account evolutionary effects besides the effect of chemical composition. Extensive tabulations of our results are provided, including convenient analytical formulae for the calculation of the coefficients of the period-luminosity relation in the different passbands as a function of HB type. We also provide "average" PL relations in IJHK, for applications in cases where the HB type is not known a priori; as well as a new calibration of the MV-[M/H] relation. These can be summarized as follows: and

• NEW OPTICAL REDDENING MAPS OF THE LARGE AND SMALL MAGELLANIC CLOUDS (2011, methodology): “Then we use the metallicity dependent relations for the V- and I-band, found by Catelan et al. (2004) by theoretical modelling of lightcurves, to infer the absolute colour (V − I)0 of each star.”
• The Galaxy in Context: Structural, Kinematic, and Integrated Properties (2016, background): “RR Lyrae stars, pulsationally unstable HB stars with characteristic absolute magnitudes M I =0.2, M K =−0.5 (Catelan et al. 2004), are the primary distance tracers for old, metal-poor populations.”
• A Multicolor and Fourier Study of RR Lyrae Variables in the Globular Cluster NGC 5272 (M3) (2004, result): “This is in agreement with the most recent synthetic HB models by Catelan et al. (2004) that would predict < MV >∼0.6 at log Z=–3.06 (corresponding to [Fe/H]=–1.5 with α-element enrichment +0.3).”
• THE AGES OF 55 GLOBULAR CLUSTERS AS DETERMINED USING AN IMPROVED METHOD ALONG WITH COLOR–MAGNITUDE DIAGRAM CONSTRAINTS, AND THEIR IMPLICATIONS FOR BROADER ISSUES (2013, background): “Still, it would be much more instructive to compute synthetic HB distributions for comparisons with the observed HB populations (see, e.g., Cassisi et al. 2004, Catelan et al. 2004) as they have the potential to discriminate between different possible interpretations of the data.”
