Ah ok, it seems that increasing a lot the number of bins the two approaches are matching better... is there any reason for that?
A second question: how it works for the electrons? In enzo the electrons are usually initialized considering a factor of mp/me, YT takes into account this rescaling?
Thanks again Stefano

ah... I'm binning, it also depends on the number of bins I'm using, but the discrepancy (slight) is still there):
prof3 = BinnedProfile1D(sph3, 64, "Radiuspc", 1.0e-6, 1.0e6)
In my initial setup I'm using a box of 300 pc.

Hi Matt, thanks for the quick reply. I'm using simple data from the enzo Collapse Test (27). It seems is mainly related to the size of the sphere I'm taking... but I don't know.
Here following a piece of my script:
pf3=load("DD0003/DD0003") c3= pf3.h.find_max("Density") sph3 = pf3.h.sphere(c3, (100, 'pc')) prof3.add_fields("H2I_Density") prof3.add_fields("H2I_Fraction") prof3.add_fields("Radius")
d_ax2.loglog(prof3['Radius'], prof3['H2I_Density']/prof3['Density'], lw=1.5, linestyle='--', color='r') d_ax2.loglog(prof3['Radius'], prof3['H2I_Fraction'], lw=1.5, linestyle=':', color='y')
Thanks in advance Stefano

Hi Guys, I did a simple test with enzo and I tried to plot a radial profile of
chemical species fractions with YT.
The problem is that if I use the YT function which intrinsically plot
fraction for a species, let's say H2I_Fraction (as usual), and compare
with a direct evaluation of the mass fraction:
I obtain some slightly different results, mostly at large radii.
Anyone might explain this discrepancy!? This happens with all the
Without knowing what "data" here is, or how you generated it, it's tough to say.
