Z MZAMS(M) MWD(M) log (MH/M) C/O

0.0001 0.85 0.535 −3.304 0.301
0.0005 0.80 0.509 −3.231 0.241
0.0010 0.85 0.538 −3.434 0.307
0.0180 1.00 0.521 −3.543 0.005
0.0001 1.50 0.666 −3.851 0.264
0.0001 2.00 0.738 −4.347 11.477

notes. MZAMS: initial mass, MWD: white dwarf mass, log (MH/M): logarithm of the mass of the hydrogen envelope at the maximum effective temperature at the beginning of the cooling branch, C/O: surface carbon to oxygen mass ratio at the beginning of the cooling branch.
