out_mat_hs  1 5
ks_solver       scalapack_gvx
out_ndigits 5

1. I want to know if the second parameter of out_mat_hs is different with out_ndigits, what will happen?

2. Why only out_band and out_mat_hs have the second parameters, how about other output variables?

In the past the out_ndigits controls precision of output in a wider range, while out_mat_hs only controls precision of output of itself. I think all the output flags can be re-designed, after re-design of input.
