hi Bruno,
Just looking through the log, there's one point which needs clarification:

15:44 <@boud> rSLS is close to 9.5h^{-1} Gpc (where you can put in h = 0.71 = H_0 / 100km/s/Mpc is the Hubble constant) 15:45 <@boud> it only changes slowly if we change Omega_total and/or Omega_matter 15:45 < Bruno> but would be the size at t=380 000 years, right? 15:46 <@boud> yes
9.5 h^{-1}Gpc is the radius (not diameter) of the SLS, i.e. of the sphere corresponding to light which was emitted at roughly this age of the Universe and is observed now near the Earth/Sun, in comoving units.
To get "local or physical" units, divide by 1100, i.e. the radius of the SLS was at that time about 8.6 h^{-1} Mpc.
This gives the diameter of the SLS at about 19 h^{-1} Gpc in comoving units, or 17 h^{-1} Mpc in local (physical) units.
