Notes. Column 1: field name. Column 2: minimum background column density in each field (see Sect. 2.3). Column 3: persistence threshold used in DisPerSE corresponding to the minimum rms level of the background column density fluctuations in each field. Column 4: robustness threshold used in DisPerSE, corresponding to 1.5, where
is the minimum background column density in each field. Column 5: total number of filaments extracted in each field following the procedure explained in Sect. 2.2. Column 6: number of selected filaments with AR > 3 and column density threshold C0 > 0.3 in each field (see Sect. 3.5).
