Every file shows the complete pre-explosive heavy-element abundances in the outermost layers of the exploding white-dwarf. There is one file for one specific lagrangian mass-coordinate location, which is specified by the name of the file itself in the following way.

Every file is named as 'ovav_mAAAmCCC.txt'. AAA and BBB specifies the two mass-coordinates (in solar masses) within which the the initial abundaces detailed in the file are valid. For example, 'ovav_m1p288m1p346.txt' means contains the pre-explosive heavy-element distribution to be adopted between mass coordinate 1.288 Msun and 1.346 (Msun). The center of the white dwarf is at mass coordinate 0 Msun.

All the chemical abundances are expressed in mass fraction. The first two lines of every file specifies the metallicity of the accreted material and the mass of the accreting white dwarf that was originally used to compute these abundances.
