Left: Two-dimensional reconstruction of the filament network using the spectroscopic sample (green segments) and photometric members (red segments) in the SSC core. The gray map indicates the density of photometric members in the area, while blue circles are the spectral members. Orange circles indicate known X-ray clusters in the SSC (Haines et al. 2018). Right: Probability distribution of the distances between skeletons of filament networks from photometric to spectroscopic (orange curve) and spectroscopic to photometric (green curve) members within the ShaSS area. Vertical dashed orange and green lines show the median distance between skeletons obtained from the two comparisons.
