Version 0.19

The first line of version-0.19 MESA-format files is a header with the following columns:

Column	Symbol	Datatype	Definition
1	\(N\)	integer	number of grid points
2	\(M\)	real	stellar mass [\(\gram\)]
3	\(R\)	real	photospheric radius [\(\cm\)]
4	\(L\)	real	photospheric luminosity [\(\erg\,\second^{-1}\)]
5	19	integer	version number

The subsequent \(N\) lines contain the model data, one line per grid point extending from the center to the surface, with the following columns:

3	\(\frac{M_{r}}{M-M_{r}}\)	real	transformed interior mass
4	\(L_{r}\)	real	interior luminosity [\(\erg\,\second^{-1}\)]
5	\(P\)	real	total pressure [\(\barye\)]
6	\(T\)	real	temperature [\(\kelvin\)]
7	\(\rho\)	real	density [\(\gram\,\cm^{-3}\)]
8	\(\nabla\)	real	temperature gradient
9	\(N^{2}\)	real	Brunt-Väisälä frequency squared [\(\second^{-2}\)]
