For this purpose, we analyze high resolution spectra obtained by the NARVAL spectrograph for a sample composed of bright planet host stars in the northern hemisphere. The new parameters are included in the SWEET-Cat online catalogue. To ensure that the catalogue is homogeneous, we use our standard spectroscopic analysis procedure, ARES + MOOG, to derive effective temperatures, surface gravities, and metallicities. These spectroscopic stellar parameters are then used as input to compute the stellar mass and radius, which are fundamental for the derivation of the planetary mass and radius. Description: The spectroscopic data were collected between 16 April 2013 and 20 August 2013 with the NARVAL spectrograph located at the 2-meter Bernard Lyot Telescope (@ Pic du Midi). The data was obtained through the Opticon proposal (OPTI- CON_2013A_027). Table 1 contains the spectroscopic parameters derived with ARES+MOOG for the sample of planet hosts analysed in this work. Table 2 contains the stellar mass and radius estimated for the planet hosts analysed in this work.
