We report the detection of an additional planet - GJ 581e - with a minimum mass of 1.9M{earth}. With a period of 3.15 days, it is the innermost planet of the system and has a ∼5% transit probability. We also correct our previous confusion about the orbital period of GJ 581d (the outermost planet) with a one-year alias, benefitting from an extended time span and many more measurements. The revised period is 66.8 days, and positions the semi-major axis inside the habitable zone of the low mass star. The dynamical stability of the 4-planet system imposes an upper bound on the orbital plane inclination. The planets cannot be more massive than approximately 1.6 times their minimum mass. Description: The paper reports the discovery of a 1.9M{earth} planet orbiting the nearby M dwarf GJ 581 (already known to host 3 planets). Here we list the radial-velocity data measured with HARPS (a high-resolution spectrograph providing high precision radial velocities) and the spectroscopic indices measured on the same spectra.
