Abstract

CARMENES is an instrument designed to search for extrasolar planets around M dwarfs with the radial-velocity technique. It consists of two independent high-resolution echelle spectrographs for the visible and near-infrared wavelength ranges, which are simultaneously fed through fibers from a front end at the Cassegrain focus of the 3.5m telescope at Calar Alto, Spain. CARMENES was installed in late 2015 and has been operated almost continuously since Jan 1st, 2016, with only a brief interruption due to the Covid pandemic. The first five years were mostly dedicated to a large survey carried out by the CARMENES consortium. Currently the instrument supports two “legacy” programs and a number of smaller projects. On-site operations are performed by the observatory staff, while the instrument team still provides services such as automated scheduling, monitoring of instrument health and data quality, and pipeline processing of all data. Joint efforts have been necessary to implement measures to improve the performance, and to address occasional problems and failures.
