The background model must be convectively stable. The points at which the grid are sampled are typically
distributed according to the criterion that the points per wavelength be maintained roughly constant with depth.
Here are a set of routines to compute the appropriately sampled background models (for a polytrope with
an isothermal atmosphere; and for the altered model of Hanasoge et al. (2006) ):
Various IDL codes
Here are a couple of sample models, ready for use:
Altered form of model S
Polytrope with isothermal atmophere
To compute the power spectrum and collate the output, use this.
To compute the magneto-hydrostatic (MHS) state for given flux, tube size, and background model;
the self-similar Schluter-Temesvary technique, use this IDL code. Note that this code can also be used to convert
a cylindrical co-ordinate description of an MHS state to Cartesian co-ordinates.
The following two libraries are required to compile and run the code in its current form:
The message passing routines are written in accordance to OpenMPI.
Many thanks to D. Dombroski (CORA), H. Schunker (MPS), H. Moradi (MPS), for being patient
and assisting significantly in debugging the code. A. Birch (CORA), R. Cameron (MPS), and
L. Gizon (MPS) have been very helpful and supportive.
