The filenames are of the form:

120_119p61_2p0.awa
120_119p61_2p0.dat

1) 120 is the zero age mass.
2) 119.61 is the current mass.
3) 2.0 is the metallicity relative to solar.
4) .awa is the input file.
5) .dat is the MERGESPEC file.

Because the models crashed for a couple of grid points I made these
changes to the original grid:

MODEL          PARAMETER GRID     USED

100_70p95_2p0. Teff	 35514.   35510.
100_51p76_2p0. Teff	 31526.   31530.

The models cover zero age masses from 120 to 50 solar masses.
