A multipurpose 3-D grid of stellar models
  The last two decades have produced a proliferation of stellar atmosphere
grids, evolutionary tracks, and isochrones which are available to the
astronomical community from different internet services. However, it is not
straightforward (at least for an inexperienced user) to manipulate those models
to answer questions of the type: What is the spectral energy distribution of a
9000 K giant? What about its J-band magnitude for different metallicities? What
can I tell about the mass of a star if I know that its unreddened B-V color is
-0.05 and its luminosity in solar units is 10^5? The answers to those questions
are indeed in the models but a series of transformations and combinations
involving different variables and models are required to obtain them. To make
the available knowledge more user friendly, I have combined a number of
state-of-the-art sources to create a 3-D (effective temperature, luminosity,
and metallicity) grid of stellar models for which I provide calibrated SEDs and
magnitudes as well as auxiliary variables such as mass and age. Furthermore, I
have generated a grid of extinguished magnitudes using the recent Ma\'iz
Apell\'aniz et al. (2012) extinction laws and incorporated them into the
Bayesian code CHORIZOS (Ma\'iz Apell\'aniz 2004).
