Instructions for Visiting Astronomers

The offered instrument modes and configurations are the same in service and visitor modes. In both cases, to prepare the observations it is necessary to:


  • Check the Instrument News
  • Define the observing strategy and decide on the templates to be used
  • Know how to use p2 and prepare the observing blocks (OBs)
  • Have a clear idea of the overheads and check the ESPRESSO ETC
  • Check the available Observing Tools

    In addition, visiting astronomers are advised to prepare a backup program in case of strong winds (pointing restriction of the telescope - usually from North), and/or bad seeing.

    Backup targets, as well as additional/change of targets, or change of instrument setups, must be requested following these instructions.

    More general information about VM runs can be found here.

    Instrument-related questions before the VM run should be addressed to espresso at Any VM run normally includes two days at the observatory before the first night of observations, during which the observing strategy is discussed and finalized with the help of ESO support astronomers.
