Users are strongly encouraged to contribute to the ongoing refinement of PASE by sending feedback.

The PASE project has sought to make the dataset as comprehensive and as accurate as possible, but in an exercise of this scale, it is inevitable that the dataset will contain omissions which need to be made good, mistakes which need to be corrected, and technical enhancements which could be implemented. One of the major advantages of publishing PASE online is that it is possible publish refinements on a regular basis. The intention is to update the website to take account of these refinements once a year. Feedback will be gratefully received at any time, and will be acknowledged in subsequent editions.
