Warning!!

After the first upgrade of the programmatic interfaces the past Tuesday, a second and final one is planned for Tuesday 2021-05-11; please expect a downtime of the TAP (tap_obs), datalink, and SSAP servers for few hours in the morning. 

The issue with the table of raw observations, dbo.raw, served via TAP/programmatic access, has been solved. Beware that its usage, on 15/04/2021, would have resulted in no records returned. Please check if that could have had an impact on you. Sincere apologies.

Due to the evolution of the pandemic situation in Chile, operational activities at La Silla Paranal Observatory have been further reduced as of April 16 and until at least May 7. More detail...
