Notes. Median and percentiles of the distributions of the differences ΔX between the aperture-free integrated index X and the values of the index as measured in the fiber (correction = “None”), the fiber index corrected at the first order (correction = “1st order”, and the fiber index corrected at the second order (i.e., first- and second-order corrections applied, correction = “2nd order”), for six absorption indices (columns 2–7) and three sets of simulations at z = 0.05, 0.1, 0.2. In each column we report the median along with the 16th and 84th percentiles in square brackets.
