Fig. 3: TL-dating results.
From: Testing a hypothesis of technology transfer in the 1100’s between Italy and Denmark
Average TL-dates for the 32 wall segments in the four churches investigated in this study shown on a time range from AD 600 to 1850. a The entire dating range; b the interval from AD 1050 to 1300. The average dates are indicated by red dashed lines with the average date and one standard deviation attached to each of them. Dates identified as outliers are marked by a green circle. These were omitted when taking the averages. In the three instances where a date was older than expected a corrected date was produced using an environmental radiation of 1/1 (4 π steradians) of the samples in the wall segment changes instead of ½ of the environmental radiation of the wall itself (a half-space of 2 π steradians). See text for explanation. These corrections are marked by blue arrows.
