Policy Statement on the Inclusion of Uncertainty Estimates for Theoretical Papers in Physical Review A

The following policy statement was discussed and approved by the Editorial Board of Physical Review A in May 2008.

Papers presenting the results of theoretical calculations are expected to include uncertainty estimates for the calculations whenever practicable, and especially under the following circumstances:

1. If the authors claim high accuracy, or improvements on the accuracy of previous work.
2. If the primary motivation for the paper is to make comparisons with present or future high precision experimental data.
3. If the primary motivation is to provide interpolations or extrapolations of known experimental data.
