[yt-users] need to set omega_baryon in yt-3

That did the trick, thank you!

Now, followup question: I am also attempting to create a 2D phase plot of
the same quantity (baryon_overdensity vs. temperature), and yt.PhasePlot
does not seem to take the field_parameters dictionary, and neither does
yt.create_profile.  Should I try another avenue to create a phase plot?
