Some features for our catalogue:
ranging from redshift z=0.050--0.700 (including MGS, LOWZ, and CMASS sample for the SDSS)
one-dimensional curves as filaments
well-defined orientation for each point on filaments
error measurements at each point on filaments
strong agreement with redMaPPer cluster catalogue
consistent to the Voronoi model
