Stratigraphy and luminescence data for colluvium at Gut Frankenforst. (A) High-resolution pOSL data and associated age-depth model against OSL control ages for sediment core GFF 5. Uncertainties of control ages are masked due to the size of the red dots. (B) Transfer functions between pOSL and deposition age based on OSL ages from GFF 3 and 5. Sections used for different transfer functions are marked in dark red for Eq. (1) and light red for Eq. (2). Residuals between OSL control ages and pOSL ages show a normal distribution around a mean of ~ zero.
