Truncation factors for median-filtered sources (
, 
) and filaments (ℱG, ℱP) using sliding windows with different radii W = R/H, corresponding to the images described in Sect. 2.1 and their profiles plotted in Fig. 1.

Notes. The factors are defined as the ratio fT = IP/IF of the original peak intensity to the filtered peak intensity. For the images with background, fT were computed in background-subtracted images. Some entries for the largest windows present additional information with respect to the plots in Fig. 1.
