Functions/Subroutines
subroutine	int_point_peskin_o4_init ()
	Init all the schemes.

subroutine	t_int_point_peskin_o4_1d_init (self)

subroutine	t_int_point_peskin_o4_1d_compute_stencil (self, coordinates, derivative, control_volumes)
	Compute the stencil values. Peskin interpolation with 4 points.

subroutine	t_int_point_peskin_o4_2d_init (self)

subroutine	t_int_point_peskin_o4_3d_init (self, spatial_dimension)

pure double precision function	peskin_dirac (x, delta)
	The Peskin's Dirac approximation.

pure double precision function	peskin_dirac_unnorm (x, delta)
	The Peskin's Dirac approximation This version avoids to multiply by \(1/\Delta\) which would cancel if multiplied back by \(\Delta\).
