We calculate how accurately parameters of the short-period binaries (10-4 Hz ≲ f ≲ 10-2 Hz) will be determined from the gravitational waves by the Laser Interferometer Space Antenna (LISA). In our analysis, the chirp signal, , is newly included as a fitting parameter, and dependence on the observation period or wave frequency is studied in detail. Implications for gravitational wave astronomy are also discussed quantitatively.
