However, constructing stellar-mass complete spectroscopic samples at low masses is increasingly difficult, and the potential existence of a local void complicates studies in an average environment. The Photometric object Around Cosmic webs (PAC) method, which combines deep photometric and spectroscopic data to measure the excess surface density $\\bar{n}_2w_{{\\rm{p}}}(r_{\\rm{p}})$ of photometric objects around spectroscopic tracers, offers a promising path forward.
