EOSgenerators.Compose_eos.read_Lal(filename, eosdir='./filesLaL/')[source]

Read the equation of state file in the LAL format, a number of tables is available at https://git.ligo.org/lscsoft/lalsuite/-/tree/master/lalsimulation/lib

Parameters:

  • eosdir (character string) – name of the directory where the EoS files are stored (default is filesCompose)

  • filename – name of the LAL format equation of state file with extension

Returns:

numpy array pressure (dyne/cm^2): numpy array eosname: character string with name of the EoS stored in the table

Return type:

energy density (g/cm^3)

EOSgenerators.Compose_eos.read_README(eosdir)[source]

Routine to read the information about the EoS model from the README(.txt) file

Args: eosdir: directory in which the README file is

Returns: eosname: name of the eos.

EOSgenerators.Compose_eos.read_compose(eosdir='./filesCompose', eos_prefix='/eos', nptsmin=100, eosname=None)[source]

Routine which reads the data from the original EoS model, Compose format is assumed

One first check is performed on the data: 1. Minimum number of grid points > nptsmin (default is 100)

Parameters:

  • eosdir (character string) – name of the directory where the EoS files are stored (default is filesCompose)

  • nptsmin (int) – required minimum number of grid points

  • eos_prefix (character string) – prefix of the eos file names, default is “eos”

Returns:

numpy array pressure (dyne/cm^2): numpy array eosname: character string with name of the EoS stored in the table

Return type:

energy density (g/cm^3)
