Projections of FITS cubes
by Nathan Goldbaum July 7, 2014

July 7, 2014

Hi all, I think this question is primarily for John ZuHone, but please feel free to jump in. I'm currently looking at the FITS frontend for my scipy talk. I just made a projection of the M33 HI data cube we have on the data hub. The image is here: http://i.imgur.com/kcw98g8.png I know that we decided to not try to jam WCS axes into the PlotWindow code, instead reserving that for PlotWindowWCS. I agree with that. However, I'm confused about the units of the z-axis. Presumably, the units … [View More]

print statements in cython
by Britton Smith July 5, 2014

July 5, 2014

Hey yt-devs, I'm trying to debug some Cython routines and want to throw in some print statements. However, when adding a simple python print statement I get the following compile error: Python print statement not allowed without gil Is there other way to do this here? Any other Cython debugging tips people have would also be very welcome. Britton

Particle field generation in 3.0
by Cameron Hummels July 3, 2014

July 3, 2014

Hello everyone, As I'm updating some of the documentation in 3.0 to be current on field generation, I thought of something that might make the particle fields a bit more clean as we build on them in the future. As I understand it, each particle type from a given code will generate its own namespace for those native particle quantities. So for example a Gadget binary dataset will read in its star, gas, and DM particles as: ('star', 'particle_mass') ('gas', 'particle_mass') ('DM', '… [View More]

Issue #853: The Kelvin unit looks lonely (yt_analysis/yt)
by John ZuHone July 2, 2014

July 2, 2014

New issue 853: The Kelvin unit looks lonely https://bitbucket.org/yt_analysis/yt/issue/853/the-kelvin-unit-looks-lonely John ZuHone: I propose (half seriously) that we add the Rankine temperature unit, so the poor Kelvin doesn't have to occupy this space all by itself: http://en.wikipedia.org/wiki/Rankine_scale Responsible: jzuhone

Cosmology class, cosmological parameters
by John ZuHone July 2, 2014

July 2, 2014

What is the source for the default values of the cosmological parameters in yt.utilities.Cosmology? It looks like WMAP7, but we haven't exactly said where.

Small adjustment for the PhasePlot API
by Nathan Goldbaum July 2, 2014

July 2, 2014

Hi all, There's a minor issue with the PhasePlot class that I'd like to fix - unfortunately fixing it implies an API change. Before I issue a pull request I'd like to ask the group what they think. Right now a PhasePlot can be created in two ways. Both are via the PhasePlot constructor. The first uses what we have in the docs: ph = PhasePlot(dd, 'density', 'temperature', ['cell_mass', 'cell_volume']) The second is via the profile keyword argument: profile = create_profile(dd, ['density',… [View More]

Example usage for triangle_facets callback?
by Nathan Goldbaum July 2, 2014

July 2, 2014

Hi all, I'd like to update my open plotting docs PR ( https://bitbucket.org/yt_analysis/yt/pull-request/985/updates-for-the-narra…) with examples for a few of the new plot callbacks in yt-3. I have examples for everything except for annotate_triangle_facets. Does anyone have an example usage for the triangle_facets callback? I believe this was added for the work to support MOAB/PYNE. -Nathan

Occulus
by Matthew Turk July 1, 2014

July 1, 2014

Hi all, Does anybody have an Occulus Rift dev kit? If so, are you by any chance going to SciPy this year, and/or able and willing to transmit the kit to someone who is going? Alternately, anybody happen to have a Google Cardboard? -Matt
