Sunspot

In order to understand the influence of magnetic fields on the propagation properties of waves, as derived from different local helioseismology techniques, forward modeling of waves is required. Such calculations need a model in magnetohydrostatic equilibrium as an initial atmosphere through which to propagate oscillations. We provide a set of the IDL routines to create a magneto-static sunspot model in equilibrium from the sub-photospheric to chromospheric layers for a wide range of parameters. The method combines the advantages of self-similar solutions and current-distributed models. A set of models already calculated by this method are also provided. The steps are described in main.pro. The parameters of the magneto-static equilibrium model can be adjusted directly in this routine. More information in Khomenko, E., & Collados, M. 2008, ApJ, 689, 1379
