Notes. Columns: (1) field name. (2) Number of filaments with contrast C0 > 1 for which a Plummer fit with fixed power-law index p = 2 was possible in each field. We derived reliable Plummer fits for 108 filaments with C0 > 1 corresponding to 73% of the selected filament sample with C0 > 1. It was possible to derive reliable Plummer fits for 61% of the filaments of the selected sample with C0 > 1. (3) Median flat inner diameter Dflat (1) = 2Rflat(1), and equivalent standard deviation (scaled from the measured interquartile range), derived from Plummer fits with fixed p = 2 in each field. (4) Number of filaments with C0 > 1 for which a Plummer fit with free power-law index p was possible in each field. Reliable fits were possible for a total number of 79 filaments with C0 > 1. (5) Median Dflat (2) = 2Rflat(2) value and equivalent standard deviation derived from Plummer fits with free power-law index p in each field. (6) Median p value and equivalent standard deviation derived from Plummer fits with free power-law index p in each field.
