The original version of this article contained incorrect calculation of recombination centre density, ρ’, and therefore all ρ’ and fading-corrected age were re-calculated. This erratum provides corrected Table 3, Fig. 4, Fig. 6 and Fig. 7 , as well as a list of corrections in the text.

Results of plRIR dating using different first IR stimulation temperaures. n is number of aliquots, ρ' is the dimensionless recombination centre density (Huntley, 2006). Residual dose was De after artificial sunlight bleaching for 3 h except for modern beach sand (gsj14-019) which was bleached for 800 h. Fading correction was performed based on Kars et al. (2008) and Kars and Wallinga (2009). To calculate the uncorrected ages, residual dose of modern beach sand (gsjH-019) was subtracted from De of each sample. Do values were calculated based on Wintle and Murray (2006). a Terrigenous sediments.b If the average g-value of samples from site 2 was lower than zero, fading correction would not performed.

(a) Uncorrected and (b) corrected pIRIR ages of gsj13-039 and gsj13-094 obtained with different first IR stimulation temperatures. The error bars show one standard error.
Fig. 7
Columnar sections as in Fig. 2. For sites 1 and 2, the fading-uncorrected and -corrected ages of the pIRIR50/290 and pIRIR200/290 signals are shown with one standard error. For site 2, the fading corrected ages of pIRIR200/290 signals were not calculated because the average ρ’ value was lower than zero. For each site, the vertical gray bar shows the expected age range.
