A major technical intervention was completed on ESPRESSO in May to address the instrument stability and the detector system performances. The improvement has been noticeable, achieving an internal drift below 10 cm/s and the detector’s readout noise below 6e- for the fast readout mode. The instrument is back in operation. The updated ESPRESSO performances will be included in the next version of the User Manual.
