La Silla Paranal Users Workshop

La Silla Paranal Users Workshop - Part II:
Optimising Phase 1 proposal planning and submission

ESO Garching, March 3, 2021 - Online event

If you are interested  learning how to prepare Phase 2 material using the associated Phase 2 tools (p2 OB preparation and submission tool, ObsPrep, p2fc, and p2API), please check the website for the Part III of the 2020/2021 Users Workshop:




ESO's ground based observatories located in Chile serve a very diverse astronomical community. The La Silla Paranal observatory (LPO) offers observations with a variety of telescopes, instruments and observing modes, including both Visitor Mode and Service Mode observations. Furthermore, the observatory provides support to its users, follows closely the quality of all observations and status of its instruments, archives the data, and for many instruments delivers science grade pipelines and reduced data products. This level of support relies on a complex machinery that although efficient may be daunting for our user community. In a spirit of transparency and availability, ESO is hereby reaching towards its users to present the various tools and services available, and at the same time, provide help in improving the technical side of their proposals and in reducing the data obtained with instruments in La Silla and Paranal.


Thus, ESO is organising the La Silla Paranal Users Workshop, a series of online events, the second of which will consist of a 3-hours meeting which takes place on March 3rd, 2021. If you are a La Silla Paranal Observatory user and are interested in the most up-to-date information, learning how to write competitive observing proposals and to use associated Phase 1 tools, e.g. the Exposure Time Calculator and the new p1 proposal submission tool, this second instalment of the workshop is for you!

Further aspects on the use of archive data and the data reduction pipelines have been presented in the first part of the workshop series, the LPO Users Workshop Part I, while planning of the observations of the approved program (Phase 2) will be dealt with in Part III, foreseen to happen in early Summer 2021.


  • Instruments available (recent updates and news)

  • Applying for LPO time, where to get information?

  • How to use the Exposure Time Calculator (ETC) and the new phase1 proposal submission tool (p1)

We plan to have the workshop on Wednesday, March 3rd, in the European morning. Registration is encouraged, but not mandatory. We will publish the link to the event on this page the day before the event.
