The effect of the recently obtained 2nd post-Newtonian corrections on theaccuracy of estimation of parameters of the gravitational-wave signal from acoalescing binary is investigated. It is shown that addition of this correctiondegrades considerably the accuracy of determination of individual masses of themembers of the binary. However the chirp mass and the time parameter in thesignal is still determined to a very good accuracy. The possibility ofestimation of effects of other theories of gravity is investigated. Theperformance of the Newtonian filter is investigated and it is compared withperformance of post-Newtonian search templates introduced recently. It is shownthat both search templates can extract accurately useful information about thebinary.Comment: 34 pages, 118Kb, LATEX format, submitted to Phys. Rev.
