Ah I've just found unit_view
on Atmosphere
. That is very useful!
Indeed, the Atmosphere
constructor can also take units too through the .make_*d
statuc methods. Internally, everything is converted to SI, with the exception of wavelength in nm. This is discussed a little in the associated paper, which is supplementary to the docs (and probably the most code in an accepted ApJ article :D).
This and the .unit_view
were a compromise due to performance and a few issues I had with units behaving a little unexpectedly.
Something like .unit_view
should probably be added to the spectral output too, and I'll leave this open to address this at some point, as well as improve the documentation.
I know that this has come up in conversation at some point, but I think it would be really useful to use astropy units throughout this package, particularly at the user interface layer.
I fully realize that introduction of units is not a trivial addition and can also involve some performance penalties as well. However, the units on some inputs/outputs are sufficiently ambiguous to warrant this. For example, I was modifying the z component of the velocity on the FAL atmosphere and I was not sure what the components on the velocity were (I believe they are SI, m/s).
