0) CAP meeting [DB, PC, JH]
Final version of the talk is on the agenda page.
Presentation went very well and it was very useful. Graeme Blair, Tom Griffin as well as the committee were there. We got to make a lot of points, to all the right people, and it seemed fairly well received. Some comments from Bruno Silva (AWS) and Rob Beswick (UK SKA) afterward.
1) Any final comments on DSIT underspend bid? [DB]
DB was asked to put together longer case based on requests for peer-review purposes. George Madden asked about this @ CAP.
AD made a few requests for clarification, finalised document to be sent to SV today.
