Member Data Documentation

◆ def_mmin

mmin_simp2 o2scl::nucmass_fit::def_mmin

The value of def_mmin::ntrial is automatically multiplied by 10 in the constructor because the minimization frequently requires more trials than the default.

◆ nmf

nucmass_fit_base* o2scl::nucmass_fit::nmf

protected

This pointer is set by fit() and eval().
