How to get ap and ap0 from the discretised equation

Hi FOAMer's
I'm solving the following energy equation:
$\rho c\frac{\partial T}{\partial t}=\nabla \cdot \left( \lambda \nabla T \right)-\rho L\frac{\partial {{\gamma }_{l}}}{\partial t}$
The discretised form of the equation may be written as,
$a_p \, T_{p}^{m+1}=a_p^{old} \, T_{p}^{old}+\sum\limits_{nb}{{{a}_{nb}}T_{nb}^{m+1}}+b$
I can access to value of

using TEqn.A(), but I'm wondering about how to get $a_p^{0}$ . Anyone please give an idea.

Thanks in advance.
