Abstract

The MEFOS instrument is being regularly used at the ESO 3.6m telescope for multi-object spectroscopy. The instrument can access up to 29 targets at the 1 degree field of the prime focus. The 21m fiber bundle links a low resolution spectrograph located in the Cassegrain cage. MEFOS has been also used to evaluate the sky subtraction with optical fibers. This paper reports on the description of the final configuration of the instrument and on its performance. A brief study on the photometric and spectral stability of fibers along with the observations is also reported.
