[yt-users] Profile Plot range question

[Stephanie Tonnesen]

Hi all,

I am trying to make a profile plot of a cylindrical radial value.  So I
politely ask:

ds =
yt.load("/data/stonnes/dwarf_test_rhopress_extrarot/DD"+sys.argv[1]+"/DD44sMBherlr"+sys.argv[1])
....
my_disk = ds.disk([0.5,0.5,0.5],[0,0,1],(30,"kpc"),(0.1,"kpc"))
....
profiles.append(yt.create_profile(my_disk,"cylindrical_r","density",weight_field="cell_mass"))
....
plot=yt.ProfilePlot.from_profiles(profiles,labels=labels)
plot.set_unit('cylindrical_r','kpc')
plot.set_log('cylindrical_r',False)
plot.save()

And when my box is 96 kpc across, with a root 512 512 512 grid, 2 levels of
refinement at 20.0 times initial density, I get what I wanted, a nice
profile out to 30 kpc.

BUT, when I ask the same thing starting with a lower resolution root grid:
256 256 256, my profile only goes out to 15 kpc!

I changed my disk to have a 40 kpc radius and it made no difference.

Can anyone tell me why this is happening?  Thanks!

Stephanie
