NAME

nfw - compute Navarro-Frenk-White profile

SYNOPSIS

nfw [-u] [-v v200] [-x x1 x2 nx] [-z z0] [-c c] [-l]

DESCRIPTION

nfw computes nfw density profile. It outputs a table (in lc format if IMCAT is installed) containing:

"x " dimensionless radius = r/r200
"v " circular velocity
"r " physical radius in cm
"dr " physical delta-radius in cm
"m " mass in M_solar
"rho " physical density in g/cm^3
"sigma " physical projected density in g/cm^2
"theta " angle in arcseconds
"kappa " dimensionless surface density
Options are:
"-u " print this message
"-v v200 " circular velocity at r_200 in km/s (200)
"-x x1 x2 " min and max dimensionless radii (0.01, 100)
"-z z0 " lens redshift (0.2)
"-c c " compactness parameter (10.0)
"-l " use pure lambda cosmology (otherwise use EdeS)
