Hi Carole,

Regarding PAF and SKA_1, I'm afraid I'm unclear about this. Memo 125
and Memo 130 defined SKA_1 with single pixel feeds. As I understand
the history, there was a criticism at the system CoDR (early 2010)
that SKA was leaving too many options open, and there was a need to
make technology decisions. The result was Memo 125, and then Memo 130
with a more detailed technology description.

Is it really possible (from a management point of view) for PAF to be
selected for SKA_1?

cheers,
Steve
