The directories contain stellar models made with the Eggleton
code as described in

"Stellar evolution models for Z = 0.0001 to 0.03"

Christopher A. and Eggleton, Peter P.

All are gzipped.  Files ending .out are detailed model output while
files ending .mod are the input files for the code.

As an example

m00110z0003ov12.out

contains output for a star of mass 1.1Msun, metallicity Z = 0.0003 and
convective overshooting parameter 0.12.

Where a helium flash takes place at low masses the evolution is
continued in files of the same name but with the initial 'm' replaced
by a 'p'.
