Instrument News

  • 2018 Sep 01: the ESO Call for Proposals for Period 103 offers the possibility to use ESPRESSO in 4-UT mode to target faint sources at a resolving power of 70'000 (Medium Resolution) with two binning options (MR42 and MR84). This mode is offered in groups of consecutive nights in visitor mode only. As during Period 102, the instrument configurations (HR11, HR21 and UHR11) of the ESPRESSO 1-UT mode are offered in both service and visitor modes.
  • 2018 Mar 01: the instrument is offered to the community for the first time through ESO Call for Proposals for Period 102. In Period 102, ESPRESSO is offered for regular operations in 1-UT mode only, in both of its two High-Resolution (HR) modes and in Ultra-High Resolution (UHR) mode. The ESPRESSO 4-UT mode may be offered in Period 103, depending on successful commissioning during Period 101. The Laser Frequency Comb (LFC) is operational at this time but not yet fully tested. LFC frames will anyway be taken by the Observatory as additional calibrations to benefit from the full precision of ESPRESSO once pipeline recipes are optimized.
