Stellar populations contain the most important information about There may also exist a relatively weak positive tendency between GRBs optical band peak times and their spectral time lags. This correction scheme can be applied to perturbed two-body and N-body problems in the solar system. This is mainly because the progenitors of present day low mass subhaloes have larger concentration parameters in the NHD than DMO simulations.
