Robert, further to mails yesterday I enabled EPS-3 on the basic service this morning and appear to be getting some ASCAT data from Metop C. However I am not seeing any data on EPS-3 from Metop B.
I have not checked but I assume there will be ASCAT data on EPS-3 on the HVS-1 service from Metop A. To be honest there is much more ASCAT data available for all three Metops on EPS-Africa which includes global and EARS.
