The data used to create the efficiency correction. a The absolute efficiency calculated from the experimental and simulated calibration sources. b The data points with the two fits as discussed in the text and the superposition of the two functions which was used for the efficiency correction. The points show the ratio of experimentally measured and simulated efficiency for the calibration sources with their standard uncertainties. c The residuals of the fit to the data. The error bars on the residuals are the standard uncertainty of each data point and the dashed lines represent the uncertainty of the logarithmic fit
