Pre-run shock grids

Shock models are extremely difficult to run. It is therefore not possible to run shock models from this website. However, Mark Allen and Ralph Sutherland have run a large shock grid with a wide range of parameters that should be suitable for most purposes. These pre-run grids are available for shock models with a wide range of shock velocities from v=100 to 1000 km/s, and four metallicities: lmc, smc, solar, twice solar. The models available include the precursor and shock emission for all shock velocities (100, 150, 175, 200, 225, 250, 275, 300, 325, 350, 400, 450, 500, 550, 600, 650, 700, 800, 900, 1000 km/s). The spectrum files include four spectra (Fnu vs E) for each velocity:
XXXX0001.sou = shock downstream, through the back
XXXX0002.sou = shock upstream, out the front
XXXX0003.sou = precursor + shock upstream absorbed through precursor
XXXX0004.sou = precursor only

Use of these shock grids requires a reference to Allen et al. (2008, ApJ, in press)

Users wishing to run shock models for parameters not covered by the grid should either download the Mappings source code, or contact Mark Allen and/or Ralph Sutherland. All users should become familiar with the papers by Allen, Sutherland & Dopita below. To avoid errors, it is advisable to run new shock models in collaboration with Mark Allen, Ralph Sutherland and/or Mike Dopita.

For more information on Mappings shock models, please see Allen et al. (2008, ApJ, in press), Sutherland & Dopita (1993, ApJS, 88, 253), Dopita & Sutherland (1996, ApJS, 102, 161), and Dopita & Sutherland (1995, ApJ, 455, 468).
