Popis:	We study the detection accuracy of double white dwarfs (DWDs), stellar-mass black hole binaries (SBHBs), light and heavy intermediate mass ratio inspirals (IMRIs), extreme mass ratio inspirals (EMRIs), massive black hole binaries (MBHBs), and the stochastic gravitational wave background (SGWB) of astronomical origin for TianQin, LISA, and joint detection. We use a Fisher matrix analysis and consider for each source the averaged detection accuracy over a realistic range of parameters. We find that on average TianQin obtains more accurate parameter estimation for DWDs and light IMRIs, LISA for heavy IMRIs, EMRIs, MBHBs, and the galactic foreground of the SGWB, and both contribute similarly to the detection of SBHBs and the extra-galactic SGWB. Nevertheless, for all sources joint detection allows setting tighter constraints on most parameters highlighting its importance for future detection. Comment: Prepared for the proceeding of the seventh international workshop on the TianQin science mission. 9 pages, 7 figures, 7 tables
