Alternative LISA-TAIJI networks: Detectability of the isotropic stochastic gravitational wave background

In Paper I, three TAIJI orbital deployments have been proposed to compose alternative LISA-TAIJI networks: TAIJIm (leading the Earth by 20\ifmmode^\circ\else\textdegree\fi{} and $\ensuremath{-}60\ifmmode^\circ\else\textdegree\fi{}$ inclined with respect ecliptic plane), TAIJIp $+60\ifmmode^\circ\else\textdegree\fi{}$ inclined), TAIJIc (colocated coplanar LISA) LISA mission (trailing inclined). And LISA-TAIJIm network has identified as most capable configuration for massive black hole binary observation. this work, we examine performance of networks stochastic gravitational wave background (SGWB) especially comparison two eligible configurations, LISA-TAIJIp. This investigation shows that detectability is competitive LISA-TAIJIp some specific SGWB spectral shapes. capability also identical separate components determining parameters signals. Considering performances on binaries observations, could be recognized an optimal option fulfill joint observations LISA.
