Archived versions

Archived versions: These have been superseded by new and improved versions, usually because something about these versions is now known to be wrong. They are archived here so that calculations that used them in the past can be reproduced. Although the idea is that they should continue to function as they did at the time they were current, that is not guaranteed. These versions will not be updated or developed further. Current and up-to-date versions appear on the main index page.
