Member Data Documentation

double io_header_1::BoxSize

box-size of simulation in case periodic boundaries were used

char io_header_1::fill[60]

fills to 256 Bytes

int io_header_1::flag_cooling

flags whether cooling was included

int io_header_1::flag_entropy_instead_u

flags that IC-file contains entropy instead of u

int io_header_1::flag_feedback

flags whether feedback was included (obsolete)

int io_header_1::flag_metals

flags whether the file contains metallicity values for gas and star particles

int io_header_1::flag_sfr

flags whether the simulation was including star formation

int io_header_1::flag_stellarage

flags whether the file contains formation times of star particles

double io_header_1::HubbleParam

Hubble parameter in units of 100 km/sec/Mpc

double io_header_1::mass[6]

mass of particles of each type. If 0, then the masses are explicitly stored in the mass-block of the snapshot file, otherwise they are omitted

int io_header_1::npart[6]

number of particles of each type in this file

unsigned int io_header_1::npartTotal[6]

total number of particles of each type in this snapshot. This can be different from npart if one is dealing with a multi-file snapshot.

unsigned int io_header_1::npartTotalHighWord[6]

High word of the total number of particles of each type

int io_header_1::num_files

number of files in multi-file snapshot

double io_header_1::Omega0

matter density in units of critical density

double io_header_1::OmegaLambda

cosmological constant parameter

double io_header_1::redshift

redshift of snapshot file

double io_header_1::time

time of snapshot file
