no, it's not the same: ngauss = kind of gaussian broadening;
nsig = number of different gaussian broadenings used to 
calculate the double sum at EFermi appearing in the expression
of the el-ph coupling . Several different values of the gaussian
broadening are used to test convergence, as earlier explained 
on this mailing list
