Hi Kacper,

Of course - I should have noticed that. Thanks for finding that.
However, I notice that when I try to create a profile for the Dark (particle) matter I run into some trouble as well.

rpm = yt.create_profile(sp, 'radius', ['particle_mass'],
                        units = {'radius': 'pc', 'particle_mass' : 'Msun'},
                        n_bins=20, weight_field=None, accumulation=True, fractional=False)

This gives the following error:

Traceback (most recent call last):
File "EnclosedMass.py", line 35, in <module>
    n_bins=20, weight_field=None, accumulation=True, fractional=False)

ValueError: too many boolean indices

Has anyone seen this before? For the 'cell_mass' everything works fine.

Cheers,
John

Hi John,
I think that if you want to compute "total" instead of mean you need to set weight_field to None in create_profile.

Hi All,

Is the accumulation flag working in 3.0?
I tried to plot the enclosed mass in a sphere and I got some funny results.

rpm = yt.create_profile(sp, 'radius', 'cell_mass',
units = {'radius': 'pc', 'cell_mass' : 'Msun'},
weight_field='density', accumulation=True, fractional=False)

print "Mass = ", rpm["gas", "cell_mass"]

In this case bin[n-1] gives a mass of something like 0.5 Msun but when I print the totals quantity I get a value of several orders of magnitude higher and closer to what I would expect.

sp.quantities.total_quantity(["cell_mass", "particle_mass"])

Cheers,
John
