[yt-dev] proposal to replace enzo_tiny_cosmology data

[Britton Smith]

Hi all,

I would like to propose that we replace the enzo_tiny_cosmology dataset
that we store for various examples with one that has a few more physics
modules enabled.  Hilary Egan has issued PRs to yt and yt-doc for a very
nice set of absorption line fitting tools.  The recipe provided works
really well with a small cosmology simulation, but the ones we have up now
are missing some key physics (H/He chemistry and a UV background) that make
the output from the recipe look quite poor.

We have been able to make a very nice looking recipe using the same
enzo_tiny_cosmology parameter file with these additions, which do not add
significantly to the overall size of the dataset.  Additionally, none of
the existing recipes that use this data will change.  I think there will
also probably be more analysis_modules coming in the future that will
benefit from using a slightly more sophisticated example dataset.

Can we get a +/-1 on replacement?

Britton
