Talk:Radiocarbon calibration

Intersect method
Is it necessary to include the section on the intersect method, seeing as we know it to be the incorrect method? — Preceding unsigned comment added by 37.168.37.30 (talk • contribs)
 * It could certainly be removed, but I put it in as I thought it was a useful explanation, and would help clarify the right method. Mike Christie (talk - contribs - library) 23:50, 9 February 2018 (UTC)

C14 half life
As per this, another difference between uncalibrated ages and calibrated ages is that the former use an old value of 5568 years for the half-life, which differs from the correct value of 5730 years. This should be mentioned and explained in the article. Zerotalk 00:52, 11 February 2018 (UTC)
 * It's covered in the parent radiocarbon dating article, but I agree it would be best to add it here. Mike Christie (talk - contribs - library) 03:34, 11 February 2018 (UTC)`

Still confused
"Uncorrected dates may be stated as "radiocarbon years ago", abbreviated "14 Cya".[3] The term Before Present (BP) is established for reporting dates derived from radiocarbon analysis, where "present" is 1950. Uncorrected dates are stated as "uncal BP",[4] and calibrated (corrected) dates as "cal BP"." remains unclear.
