Sentence examples for calibration of dates from inspiring English sources

Calib 7.0, released in 2013, now calibrates radiocarbon ages to 50 ka and will be used for calibration of dates in Version 3 of the LaMEVE database.

Fairbanks et al. (2005) was used for calibration of dates of 26 to 50 ka.

The results of Bayesian calibration (BCal) of dates with a prior assumption of chronological ordering were compared with a Bayesian wiggle-match approach (Bpeat) which assumes constant linear accumulation over sections of the peat profile.

In the absence of any publicly available proof for the dendrochronology of the calibration curve, do we have to rely on Egyptian chronology for the calibration of carbon dating?

(Although raw radiocarbon dates must be calibrated to obtain true calendar years, which during this time period are probably several thousand years older, the precise calibration of such ancient dates is still uncertain. Thus the team has followed routine practice and reported only uncalibrated dates).

This approach also allows us to compare our results with other studies using similar combinations of fossil calibrations to date the origins of squamate groups [see [ 10, 11]].

Hurford, A.J., and Green, P.F., 1983, The zeta age calibration of fission-track dating: Isotope Geoscience, v. 1, p. 285-317.

Although current molecular clock methods offer greater flexibility in modelling evolutionary events, calibration of the clock with dates from the fossil record is still problematic for many groups.

The labelling of the six compounds with 111In was performed 9 days after 111In production (The calibration date of 111InCl3 is 10 days after the production of 111InCl3, and the expiry date of 111InCl3 is 11 days after the production of 111InCl3).

To obtain a minimum divergence time estimate of L. helicina from Arctic and Antarctic regions we also analysed the data within BEAST v1.4.8 (using a SRD06 nucleotide model and an uncorrelated log-normal relaxed clock model) using a fixed calibration date of 58.7 Ma on the divergence of Limacina (Limacinidae) and Hyalocylis (Creseinae) [29].

Our findings are in line with the poor awareness for regular checks of devices indicated by a study where 40% of the family doctors could not remember the last calibration date of their SPM (10).
