mkcflow, vmcflow: cooling flow, mekal

A cooling flow model after Mushotzky & Szymkowiak (Cooling Flows in Clusters and Galaxies ed. A. C. Fabian, 1988). This one differs from cflow in setting the emissivity function to be the inverse of the bolometric luminosity. Abundance ratios are set by the abund command. Redshift is converted to distance using the cosmology set by the cosmo command. The switch parameter determines whether spectrum is calculated by running the mekal code, by interpolating on a pre-calculated mekal table, or using the AtomDB data.

For the mkcflow model the parameters are:

par1 low temperature (keV)
par2 high temperature (keV)
par3 abundance relative to Solar
par4 redshift
par5 switch (0 = calculate, 1 = interpolate, 2 = use AtomDB data)
norm Mass accretion rate (solar mass/yr)

While for the vmcflow variant the parameters are:

par1 low temperature (keV)
par2 high temperature (keV)
par3-par16 Abundances for He, C, N, O, Ne, Na, Mg, Al, Si, S, Ar, Ca, Fe, Ni wrt Solar
par17 Redshift
par18 switch (0 = calculate, 1 = interpolate, 2 = use AtomDB data)
norm Mass accretion rate (solar mass/yr)
