The Multi-object APO Radial Velocity Large-area Survey (MARVELS) commenced operations as an SDSS-III bright-time survey in Sep. 2008. MARVELS will be used to monitor 11000 stars for RV variations during SDSS-III, using time baselines of 1.5 years, to <10-30m/s radial velocity (RV) precision for stars with brightnesses 7.6We outline our DFDI RV data reduction procedure and show calibration lamp image stability equivalent to 3m/s RMS stellar RV precision. On-sky, even in the presence of higher than normal environmental disturbances during our Sep. commissioning observations, our first preliminary analysis achieved 12m/s RMS RV precision (on 9m/s photon noise) on the RV-stable star HD 9407 (V=6.5) in 144 sec. exposures, and 30m/s RMS RV precision (on 20m/s photon noise) on the known planet-bearing star TrES-2 (V=11.4) in 40-60 min. exposures, over 6 commissioning nights. Finally, we show candidate radial velocity variables garnered after moving to normal survey operations during Oct.-Dec. 2008, acquired using an operations strategy designed to deliver optimum extrasolar planet yield over the six-year lifecycle of SDSS-III.
We would like to thank the W.M. Keck Foundation, Sloan Foundation, NSF, NASA and UF for support.
