[ T-Adjoint ] section
==================================================

This is the tally used in adjoint mode, **iadjoint=1**, calculations.
The results from this tally are equivalent to the results from a **[T-Track]** tally in the corresponding forward mode calculation.
See :numref:`sec-adjoint-mode` and the sample input file in ``/phits/utility/adjoint/`` for more details on how to set up an adjoint simulation and how to set **e-type**, **e-smin**, **e-smax**, and **factor** in this tally.

When using the function to display the transition of tally results and errors, mesh points for the tally results and these statistical errors can be specified by setting the ``anatally`` subsection.
This subsection should be defined between the lines **anatally start** and **anatally end** written in the tally section.
See :numref:`sec-extstat` for more details.
