New issue 582: HaloMassFunction uses Enzo ComovingBoxSize https://bitbucket.org/yt_analysis/yt/issue/582/halomassfunction-uses-enzo-co... Matthew Turk: (reported by @mepa ) Inside `yt/analysis_modules/halo_mass_function/halo_mass_function.py` on line 215, there's a reference to `self.pf["ComovingBoxSize"]`. I believe this is then converted into actual Mpc, not Mpc/h, and is then cubed to get the volume of the domain. I am not entirely certain, but I believe this could be replaced either by: `(self.pf.domain_width * self.pf["mpccm"]).prod()` or: `(self.pf.domain_width * self.pf["mpc"]).prod()` depending on whether the mass function is supposed to be proper or comoving; the comments in the code suggest to me very strongly it's the first of the two, not the second. @brittonsmith I am tagging you in the ticket, but if you aren't able to take a look at this feel free to re-assign to me.
