yt 3D rendering of radio data from SpectralCubeFITSDataset #925

Open HealthyPear opened 1 month ago

HealthyPear commented 1 month ago

Hi all,

I have a file from the FUGIN radio survey which I open with spectral-cube resulting in a cube with (GLAT, GLON, VELOCITY) dimensions which I slice, mask and downsample to make it easier to work with. The unit of each pixel is in Kelvin.

I attempted to follow the example here https://spectral-cube.readthedocs.io/en/latest/yt_example.html#visualization-example which uses yt to make a 3D cube rendering, but I get the error

AttributeError: 'SpectralCubeFITSDataset' object has no attribute 'camera'

From the yt documentation it is not clear to me if this is a problem of my file, or its format or if I should use other functions. I would basically want to see a 3D rendering of the gas clumps, ideally with iso contours.

Did anyone ever do this?

The yt link has gotten quite out of date, but it would be great if we could still use it.

You might want to try https://yt-project.org/doc/analyzing/astropy_integrations.html instead.

not really an expert of both these packages, I was hoping to use them for a quick check of the object I am studying...

is #586 related to this?

keflavich commented 1 month ago

Yes. If you want to try that branch out and see if it works, that would be very helpful! Otherwise, @e-koch and I can look into this a little this weekend. @jzuhone can you chime in here at all?

I can try to look at it next week.
