Hi Daniel, Thanks for telling us about this. We have a pull request <https://bitbucket.org/yt_analysis/yt/pull-requests/1768/improve-check_for_o…> open that should allow the install script to work normally when CC="ccache <compiler>" in the future.

Hello yt users, I'm working with Daniel Schwen of the MOOSE team to install yt from source. He is running OS X Yosemite, and trying to install yt over a miniconda python.

Change in SPH kernel behavior
by Matthew Turk 24 Sep '15

24 Sep '15

Hi all, I wanted to bring to your attention a change in the SPH smoothing kernel behavior. This has landed on the development version on yt, but *not* the stable, and will not be backported to stable until the next major release (3.3). Previously, a kernel normalization was applied to smoothed grid cells. This could result in mass conservation not being 100% preserved; some cases were worse than others. (Cosmology was typically fine.) The recent change has removed the normalization step. Here are some relevant PRs: https://bitbucket.org/yt_analysis/yt/pull-requests/1740/remove-normalizatio… https://bitbucket.org/yt_analysis/yt/pull-requests/1721/allow-for-neighbors… -Matt

PHOX Mock observation

Hello John! Thanks for your detailed answer. I tried your second suggestion first because it was striaghtforward and it worked! No more memory errors. Now that you specify your machine capabilities I can see why I was having problems, since I only have 8 GB of RAM. In the future I will try to make it run parallel since we do have a small cluster in our department. So I have succesfully generated a photonlist with the following parameters: (photons_per_chunk=50E6) A = 2000. exp_time = 100.0e2 redshift = 0.05 cosmo = Cosmology() (I just generated one single list, not quite sure how to do the merging yet!) Now, going further on the code, I'm trying to project those photons using the following code: ARF = "/home/barbara/yt-x86_64/xray_data/chandra_ACIS-S3_onaxis_arf.fits" RMF = "/home/barbara/yt-x86_64/xray_data/chandra_ACIS-S3_onaxis_rmf.fits" normal = [0.0,0.0,1.0] events = photons.project_photons(normal, exp_time_new=1.0e4, redshift_new=0.07, dist_new=None, absorb_model=None, sky_center=(187.5,12.333), responses=[ARF,RMF], convolve_energies=True, no_shifting=False, north_vector=None, psf_sigma=None) Which produces the following output+traceback: [INFO ] 2015-09-24 15:40:51,932 Using energy-dependent effective area: /home/barbara/yt-x86_64/xray_data/chandra_ACIS-S3_onaxis_arf.fits yt : [INFO ] 2015-09-24 15:40:52,134 Total number of photons to use: 7776596 yt : [INFO ] 2015-09-24 15:41:01,217 Applying energy-dependent effective area. yt : [INFO ] 2015-09-24 15:41:02,016 Total number of observed photons: 4518817 yt : [WARNING ] 2015-09-24 15:41:02,017 This routine has not been tested to work with all RMFs.

Any ideas? Is this related to the small photon list I'm working with? I have increased the observation redshift from 0.01 (as in the example) to 0.07 because I was obtaining another error that said: 585 fak = Aratio*Tratio*Dratio 586 if fak > 1: --> 587 raise ValueError("Spectrum scaling factor = %g, cannot be greater than unity." % fak) 588 my_n_obs = np.uint64(n_ph_tot*fak) 589 ValueError: Spectrum scaling factor = 8.78099, cannot be greater than unity. But I'll admit I fixed that purely by chance and playing with the parameters... Thanks again for working through this with me. I hope the community benefits from this discussion! PS: I'll send you anyway a private email with a copy of my dataset so you can have a better idea of the kind of errors I'm encountering -- Barbara L. Ramirez MSc.

Hello John! Sure, I hadn't understand before. Here are my object properties: R200: 1.00654482691 Mpccm/h Total Mass at R200: 3.65901447937e+14 Msun Avg Temperature at R200: 5.70273 E 7 K I tried decreasing the Area to 2000 but I'm still getting the memory error. With a photons_per_chunk of: 10 E 6 I get: RuntimeError: Number of photons generated for this chunk exceeds photons_per_chunk With an increase of 10 (10 E 7 photons_per_chunk) I get the same Runtime error, but with an increase of 100 I get memory error! Again, observation parameters: A = 2000. exp_time = 100.0e3 redshift = 0.05 Do you have any idea on how could we solve this? Thanks for your time! -- Barbara L. Ramirez MSc.

multi projection plots with title and annotations

Hello there, I'm trying to do a multipanel plot of projected density with titles in each axis and annotations but I couldn't figure out how to do it, could you please help me.

Subplots with annotations
by Mikhail Klassen 16 Sep '15

16 Sep '15

I would like to create a sequence of subplots in yt, but that contain annotations. The example from the yt cookbook shows how to create multi-plots using an AxesGrid object: http://yt-project.org/doc/cookbook/complex_plots.html However, in trying to replicate this example, I haven't managed to have subfigures that each make use of yt's annotation tools, such as annotate_scale() or annotate_streamlines(). This would be very useful to me if somebody knows how to do this. In matplotlib, one can typically just add new subplot axes, modify the plot at will, and then move on to the next set of axes. I can't seem to do this with yt and still keep my annotations. Cheers, Mikhail
