real(kind=C_DOUBLE),	intent(in),		VALUE	::	y	$y$ coordinate of the desired point
real(kind=C_DOUBLE),	intent(in),		VALUE	::	z	$z$ coordinate of the desired point
real(kind=C_DOUBLE),	intent(out)			::	g_rr	$g_{xx}=g_{yy}=g_{zz}$ at $x,y,z$
real(kind=C_DOUBLE),	intent(out)			::	g_tt	$g_{xx}=g_{yy}=g_{zz}$ at $x,y,z$

Description

Interface to the \(\texttt{LORENE}\) method of class \(\texttt{Et_diffrot}\) with the same name, that reads the hydro fields and the metric fields from \(\texttt{LORENE}\), at the specified point, needed to compute the baryon mass.

• shift vector [c]
• baryon mass density [kg m^{-3}]
• fluid 3-velocity with respect to the Eulerian observer [c]
