Hi,
Does anyone have code to create derived fields of ionization states, e.g.
HI, for ramses data sets? If that's a no, does anyone have an example of a
derived field where you have to read in a table and interpolate the field
values.
Thanks,
Ari

Hi,
according to
http://yt-project.org/docs/2.6/analyzing/creating_derived_fields.html?
what worked for me for enzo data is the following
def _HINeutralFraction(field, data):
return data['HI_Density']/(data['HI_Density']+data['HII_Density'])
add_field('HINeutralFraction',function=_HINeutralFraction,
units=r"\rho_\mathrm{HI}/\rho_\mathrm{H}")
unless there's something strange with ramses dataset, the above should work.

Hi Ari,
My reading of yt/frontends/ramses/fields.py is that this should be
implemented already, using the cooling_%05i.dat files. If it's able
to find those files, it will create the appropriate derived fields
from them -- specifically, I think it can do Electron, HI, HII, HeI,
HeII, and HeIII. Is it not creating those?
