Modules
module	specpjh
	Fortran module for SPEC Pressure Jump Hamiltonian problems.

Functions/Subroutines
subroutine, public	specpjh::get_pjhfield (phi, ptt, dptt)
	Compute the ODEs for PJH system, \(dp_\theta/d\varphi\), \(d\theta/d\varphi\).

subroutine, public	specpjh::get_pjhfield_tangent (phi, ptt, dptt)
	Compute the ODEs for PJH system, \(dp_\theta/d\varphi\), \(d\theta/d\varphi\), with tangent.

subroutine, public	specpjh::get_covariant_field (theta, phi, bco)
	Get the covariant component of known side of magnetic field \(\bf B_1\), i.e. \(B_{1,\theta}, B_{1,\varphi}\). Can be used to estimate the initial condition for \(p_\theta\).

subroutine, public	specpjh::get_b2_interface (db2, ioi, theta, phi, guvij, sg, ideriv)
	An internal subroutine that computes the squared magnetic field strength on the interface \(B_1^2\) and its first and second \(\theta\) derivatives. This is a private subroutine that is not interfaced with Python.

subroutine, public	specpjh::init_pjh (dp, inside_or_outside, plus_or_minus)
	Initialize the PJH system. Whenever \(\delta p\) is modified, you will need to call this subroutine (in Python interface) again.

subroutine, public	specpjh::destroy_pjh ()
	This subroutine frees the memory space allocated by specpjh::init_pjh.
