This release contains a significant improvement on the IGM model. The choice of the IGM model can now be controlled with the igm=... option. Available choices are:

  • none: (new) no IGM absorption is applied.
  • constant: (equivalent to the old naive_igm=1) IGM absorption is constant, and fixed to the mean absorption for z=1 galaxies in the Madau+95 model.
  • madau95: (equivalent to the old naive_igm=0) uses the Madau+95 model as implemented in FAST.
  • inoue14: (new) uses a similar model as for madau95, but based on the updated Inoue+14 prescriptions, and implementing realistic scatter caused by variation of lines of sight through the IGM. This is calibrated on Monte Carlo simulations kindly provided by Akio Inoue.
