On the failures: there seems to be a travis configuration issue, which I'm attempting to fix here: #148 |
| pixel_volume = ((spatial_scale.to(u.cm)) ** 3) | ||
|
|
||
| elif spatial_scale.unit.is_equivalent(u.pc): | ||
| pixel_volume = ((spatial_scale.to(u.cm)) ** 3) |
There was a problem hiding this comment.
this & the next line are redundant: u.cm, u.pc, and u.kpc are all equivalent
|
Besides the few comments, this looks good to me. It would be helpful to have some tests, though. |

Hello @keflavich and @dcolombo. I want to use PPP statistics to find the mass of structures (leaves) in a simulation outputs. I think this PR is very useful. But I see this PR has remained open since a long time. Could I use the fork safely? Has anyone tested it? |

Hi! I'm also interested in using this, so a status update would be handy. Are there things that I could do to help move this forward? Or should I be looking at re-writing the functionality that I need myself? |

Ana Duarte-Cabral and I created a tentative version of PPP structure catalog.
The current implementation works only on the volumetric density-based simulated data cube used to generate the dendrogram. Simulated data cubes must be provided in units of g/cm3 or Msun/pc3. Classes needs mass.py script functions which provide the mass of the structures in Msun. This is basically a mirror of flux.py of PPV catalog.
The implementation has been tested on a chunk of Clare Dobbs' simulation and appears to provide the expected results.
