Context. Radial velocity (RV) measurements from near-infrared spectra have become a potentially powerful tool to search for planets around cool stars and sub-stellar objects. As part of a large survey to characterize M-dwarfs using NIRSPEC at Keck II, we obtained spectra of eight late M-dwarfs (spectral types M5.0–M8.0) during two or more observing epochs per target. These spectra were taken with intermediate spectral resolving powers (R ~ 20 000) in the J-band.
