Figures of merit for a stochastic gravitational-wave background measurement by LISA: Implications of LISA Pathfinder noise correlations

An important goal of the Laser Interferometer Space Antenna (LISA) is to observe a stochastic gravitational-wave background (SGWB). A study possible correlated noise in LISA relevant establish limits for this future measurement. To test investigation methods under somewhat realistic conditions, we use data Pathfinder (LPF). We calculate coherence between LPF differential acceleration two test-masses with magnetic fields, temperature, and micronewton cold gas thruster activity spacecraft. apply our observed correlations LISA, estimate how presence such would affect its search SGWB. In context figure merit, effect on SGWB search.
