Carmenes DR1 Radial Velocity Time Series
The CARMENES instrument, installed at the 3.5 m telescope of the Calar Alto
Observatory in Almería, Spain, was conceived to deliver high-accuracy
radial velocity (RV) measurements with long-term stability to search for
temperate rocky planets around a sample of nearby cool stars.
The service publishes the radial velocities derived from the
CARMENES guaranteed time observations (GTO),
spanning from 2016 to 2020. This results in 362 individual
time series mapping time to radial velocities.

simpler to use the SSA service or pull them from obscore.
