Trident Data Files

Trident requires a datafile to compute ion abundances from density, temperature,
metallicity, and redshift information for gas parcels. This datafile is a large
HDF5 table consisting of outputs of many Cloudy simulations assuming collisional
ionization equilibrium and photoionization from a meta-galactic ultraviolet
background. Only one such file is required.

The first time you load Trident, it will automatically try to download/unzip a
background datafile and place it in the $HOME/.trident subdirectory. If you wish
to use additional background files, you can manually download any of the files
below. Make sure you gunzip them after downloading, and place them in the
location specified in your config.tri configuration file as described in the
installation documentation.

Note: It is most appropriate to use the self-shielding versions of the data tables
to process simulations that employ some sort of internal self-shielding protocol.
For simulations that do not have approximate self-shielding effects, use the
non-self-shielded ion tables.
