IMPORTANT NOTICE (11 July 2025 11:00CEST): we are currently experiencing a major issue with our p2 software that prevents the creation of new Observation Blocks, so that Phase 2 submissions cannot be made at this stage. We are actively investigating this issue and hope to restore p2 to its normal state as soon as possible. We sincerely apologize for the inconvenience.
UPDATE (11 July 2025 13:00CEST): the bug has been corrected. Please refresh the p2 page in your browser and make sure that you are using version 2.22.6 (or above) of the interface as indicated in the top-left corner of the page.

General Phase 2 Documentation

For a successful service mode run it is absolutely essential that all users read the following documentation.

Tutorials

P2 tutorials are available for a number of instruments. Please select an instrument from the instrument drop-down menu on the right. A dedicated test environment is available for p2 at http://www.eso.org/p2demo 

Also available are some general general tutorials on the use of scheduling containers, on the attachment of finding charts, on filling out the README, and on finalizing the overall Phase 2 submission.

Please be informed that a set of template OBs are available in the p2demo. Under each Observing Run you will able to access to the Instrument’s specific Tutorial folder, where we have stored some example OBs designed for different modes and observing strategy. Please fell free to copy and paste these OBs into your working folder. The template OBs can be also exported via the import/export function. Please do not change the content of the Tutorial folders.
