Measurement of the $e^+e^- to etapi^+pi^-$ cross section with the SND detector at the VEPP-2000 collider

The $e^+e^- to etapi^+pi^-$ cross section is measured at the SND detector in the $eta$ decay mode $etato 3pi^0$. The analysis is based on the data sample with an integrated luminosity of 32.7 pb$^{-1}$ collected at the VEPP-2000 $e^+e^-$ collider in the center-of-mass energy range $sqrt{s}=1.075-2.000$ GeV. The data obtained in the $etato 3pi^0$ decay mode are found to be in agreement with the previous SND measurements in the $etato gammagamma$ mode. Therefore the measurements in the two modes are combined.
