Due to planned IT maintenance access to ESO services will be only intermittent between Saturday, 23 Jul 2016 at 08:00 CEST and Sunday, 24 Jul 2016 at 24:00 CEST. In particular, we advise our users not to try to submit Phase 2 material during this period to avoid any problems.
OB run-time failure policy
Although ESO carefully reviews OBs before they are scheduled at the telescope, it is often impossible to detect an OB problem until it is actually executed.
If an OB fails to execute due to an error introduced by the user (as for example if the user entered wrong target coordinates), ESO reserves the right to charge the respective observing programme for the time lost during night operations. Time charged will include any telescope time used to investigate why OB execution failed.
For service mode observations time lost due to failures caused by ESO (e.g. instrument malfunction) will not be charged to the user. Whenever possible, these OBs will be re-executed as time, conditions, and overall priority permit.
