Hop vs HaloProfiler
by Agarwal, Shankar 02 Dec '09

02 Dec '09

Hi, I am a little confused as to how to use hop_circles. I tried this but it fails... from yt.mods import * fn = "RedshiftOutput0002" pf = load(fn) halos = HaloFinder(pf) halos.modify["hop_circles"](self, hop_output, max_number=None, annotate=False, min_size=20, max_size=10000000, font_size=8, print_halo_size=False, print_halo_mass=False, width=None) halos.write_out("HopAnalysis.out") Also, I tried HaloProfiler using http://yt.enzotools.org/doc/cookbook/recipes.html#cookbook-run-halo-profiler. It generated the radial_profiles/ directory with Halo_xxxx_profile.dat files. I am printing here the first few lines from Halo_0000_profile.dat... # ActualOverdensity CellVolume Density RadiusMpc Temperature TotalMassMsun myweight 2.796608e+03 9.422900e+72 1.407563e-27 1.086579e+00 4.551426e+07 3.320010e+13 3.334302e+12 1.587191e+03 1.884580e+73 3.247510e-28 1.121908e+00 3.392715e+07 3.768487e+13 7.692859e+11 1.213350e+03 3.298015e+73 8.512354e-28 1.158386e+00 3.176131e+07 5.041525e+13 2.016447e+12 9.092253e+02 5.182595e+73 7.672296e-28 1.196051e+00 3.692482e+07 5.936658e+13 1.817450e+12 Is Halo_0000_profile.dat related to the first Halo listed in HopAnalysis.out file ? What is # ? What is the meaning of ActualOverdensity ? And units ? What is the meaning of CellVolume? And units ? What is Density referring to ? And units ? What is mywieght ? I also got the projection/ directory.

Overplotting particles
by Agarwal, Shankar 30 Nov '09

30 Nov '09

Hi, I wanted to know what the simulation volume and the number of particles are for the following 2 plots.. http://yt.enzotools.org/attachment/wiki/Screenshots/s_projection_z_density.… http://yt.enzotools.org/doc/cookbook/recipes.html#overplot-particles For the first one, what is the command to plot hop-particles inside the circles ? I am using hop_circles, But it only plots circles. regards shankar

HaloProfiler vs sum_mass_in_sphere.py
by Agarwal, Shankar 30 Nov '09

30 Nov '09

Hi, I ran HaloProfiler on HaloAnalysis.out and here is the data for the first halo... # id center[0] center[1] center[2] RadiusMpc TotalMassMsun 0000 0.169329105 0.144388856 0.8246570556 3.1986507886 1.07530961369e+15 Then I ran sum_mass_in_sphere.py with the above center and radius ... from yt.mods import * fn = "RedshiftOutput0002" pf = load(fn) sp = pf.h.sphere([0.169329105,0.144388856,0.8246570556],3.1986507886/pf["mpc"]) baryon_mass, particle_mass = sp.quantities["TotalQuantity"]( ["CellMassMsun", "ParticleMassMsun"], lazy_reader=True) print "Total mass in sphere is %0.5e (gas = %0.5e / particles = %0.5e)" % \ (baryon_mass + particle_mass, baryon_mass, particle_mass) And got... Total mass in sphere is 1.27226e+15 (gas = 2.06890e+14 / particles = 1.06537e+15) Let me know if the TotalMassMsun should match. Because they don't. regards shankar KU Cosmology

Halos on slices
by Agarwal, Shankar 30 Nov '09

30 Nov '09

Hi, a couple of questions.. 1. I did pc.add_slice("Density",0). Now, I want to plot the halos just for that slice. Is it possible to plot the Halos (from HaloAnalysis.out) slice wise ? 2. I added the Density contours on the slice like... p.modify["contour"]("Density",ncont=4,take_log=False,clim=(1e-28,1e-30)) Here, if I am correct, the (1e-28,1e-30) range is divided into 4 equal intervals. So, would the contours be (1e-28,7.525e-29,5.05e-29, 2.575e-29, 1e-30) ? And which of these 5 will get plotted (the first 4? or the last 4?) In any case, I have the plot here... http://drop.io/hop_circles . And it does not show any contour with 1e-29. regards shankar

Is pc.add_projection("Density", ax) a valid statement ?
by Agarwal, Shankar 28 Nov '09

28 Nov '09

Hi, In the following code, I am getting an error when I use pc.add_projection("Density", ax). But If I specifically use pc.add_projection("Density", 0) then it runs fine. Any idea ? Code... from yt.mods import * pf = load("RedshiftOutput0002") pc = PlotCollection(pf) for ax in range(3): p = pc.add_projection("Density", ax) p.modify["hop_circles"](halos, max_number=None, annotate=True, min_size=0, max_size=100000000, font_size=8, print_halo_size=True, print_halo_mass=True, width=None) pc.save() Error....

plotting questions
by Agarwal, Shankar 24 Nov '09

24 Nov '09

Hi, I was trying the following 2 methods... from yt.mods import * p = plots.get_slice("RedshiftOutput0002", "Density", 0) p.modify["grids"]() p.modify["contour"]("Density") p.save_image("plot1") from yt.mods import * pf = load("RedshiftOutput0002") pc = PlotCollection(pf) for ax in range(1): pc.add_slice("Density", ax).modify["grids"]() pc.save("plot2") I have the plots for them attached. My simulation box is 200 Mpc/h. I wanted to know what are the default span (length scales) for the 2 methods ? For plot 1, how can I control the spacing of contours ? And where is plot 1 centered at ? For plot 2, it is centered at the most dense point in the box. But how can I add density contours ? Also, how to control the spacing ? regards shankar KU Cosmology

HOP threshold
by Agarwal, Shankar 23 Nov '09

23 Nov '09

Hi, I am generating Halos using HOP (via yt). I see that the default overdensity is 160. I guess it means 160 particles per cell. But isn't cell size a function of the simulation box volume and the grid ? For example, if Box=200Mpc and Ngrid=512^3, then cell=(0.390625 Mpc)^3 Isn't 0.390625 Mpc too big for a galaxy ? What is the calculation behind 160 ? shankar KU Cosmology
