We observed Kepler-1655 with the HARPS-N instrument (Cosentino et al. 2012SPIE.8446E..1VC) on the Telescopio Nazionale Galileo (TNG) at La Palma, Spain, over two seasons between 2015 June 7 and 2016 November 13. The spectra were processed using the HARPS Data Reduction System (DRS; Baranne et al. 1996A&AS..119..373B). The cross-correlation was performed using a G2 spectral mask (Pepe et al. 2002Msngr.110....9P). The RV measurements and the spectroscopic activity indicators are provided in Table 4. The median, minimum, and maximum signal to noise ratio of the HARPS spectra at the center of the spectral order number 50 are 51.8, 24.8, and 79.2, respectively. <P />(1 data file).
