Host file

The host file contain coordinates and peculiar velocities to simulate SN, the needed keys are given in the next table

zcos	ra (rad)	dec (rad)	vpec (km/s)
Cosmological redshift of the host	Right ascension of the host	Declinaison of the host	Velocity along the line of sight

Note that you can used the redshift distribution of your host to generate SN redshift distribution.

Extra columns are necessary if you want to use the distrib configuration key to draw hosts.

As example,

sm	sfr
The host stellar mass in arbitrary units	The host sfr in arbitrary units

can be used for “mass”, “mass_sfr” or “sfr” distrib options.
