Radiocarbon calibration anyone?

[Jacques Cinq-Mars]

All,

Just received and passing it on for your information:

A third Beta-test version of OxCal 4 is now online.

This version is substantially different from OxCal 3:

. Calibrations can be performed on post-1950 material using the Hua and Barbetti 2004 data
. New methods are included for
  . Age depth modelling
  . Sapwood estimates (for dendrochronology)
  . Non-uniform deposition models
. The new program is Web based with SVG graphics
. You can also download a version to run on a PC or Mac in combination with the Firefox browser

Information on the program can be found at:

    http://c14.arch.ox.ac.uk/oxcal.php

If you would like further information on updates to the program you can add yourself to the oxcal-announcements group (details given at
http://c14.arch.ox.ac.uk/oxcal.php#updates).  There is also a discussion group for the reporting of bugs, discussion of possible improvements to the program and for more detailed information on changes to the software.

The program will be released when tests have been completed and there has been time to respond to issues raised by users.  The manual should also be essentially complete by then.

And here is info on what I assume to be the final version of OxCal 4:

OxCal4 Released
=============

This is a completely new version of OxCal - a program which can be used for radiocarbon calibration and more general analysis of chronological information. The new version differs from version 3 in a number of ways:

. It is web-based and so can be used online without installation (assuming you have a suitable browser)
. Standalone versions are available for PC and Mac platforms
. The program incorporates many new modelling tools - including methods for age-depth modelling
. Post-bomb calibration is now possible
. All graphics are in the SVG (scalable vector graphics) format

For further information and access to the program see the OxCal website:

I haven’t had much time to explore the website, but from what little I saw, it seems to be less user-friendly than the CalPal one which can be found HERE
