Spectroscopy and <i>BVI</i><sub>C</sub> photometry of the young open cluster NGC 6604
BVIC photometry and classification spectroscopy is presented for the young open cluster NGC 6604. Additional Echelle spectroscopy of the brightest members is used to check the reddening against the interstellar NaI and KI absorption lines, to measure the cluster radial velocity and to derive the individual rotational velocities. We obtain …
