Robert I do not take ASCAT data on EPS-3, but you should be getting it on both the basic service and HVS-1. I will check tomorrow on the basic service.
Keep in mind that ASCAT data from all three Metops is also available on EPS-Africa and if you are not taking EPS-3 you can set up the Metop Managers to handle that data ( that is what I do at the moment ).
