New "consensus" radiocarbon calibration curve


The INTCAL committee has forged a revised and consensual new calibration curve, which was published of Friday
at Science magazine (found via Archaeology in Europe).

A simplified format, useful for reference for amateurs like myself is openly available:

Very roughly, for an even quicker reference: 10,000 BP means 11,500 years ago, 20,000 BP means 23,000 years ago and 35,000 BP is equivalent to 40,000 years ago. Uncalibrated dates are noted as BP, while calibrated dates are usually tagged as calBP (or similar) or even, quite informally, as "years ago". Different calibration curves can bring confusion too and therefore having a single reference curve as this one may be quite important.

It is worth mentioning in this regard the review of this matter of C
14 dates, raw and calibrated, that Julien Riel-Salvatore made a few days ago at A Very Remote Period Indeed, which is very instructive.
