34. Recommendations from P1 Review After the P1 Review, the reviewers had six items that they wanted to see addressed The following slides identify our actions to each of the six points Slide: 34 NEXPReS P2 Review – Brussels - 21 September 2012 WP 1- Management

35. R1- Revise D5.2 Revise the content of Deliverable D5.2 to include real metrics to measure reliability, availability as perceived by the user, scalability, robustness as planned in the DoW (see the comments on progress with WP5 in the review report) and resubmit before the end of November 2011. After the P1 review, WP5 Leader Szomoru exchanged emails and telephone calls over the end of November 2011 and early December 2011 with the Project Officer to clarify manner in which the project would address this issue. The commission agreed that Deliverable 5.2 was to be amended resulting in three addendums (part of the 5.2 deliverable bundle) which addressed the concerns Slide: 35 NEXPReS P2 Review – Brussels - 21 September 2012 WP 1- Management

36. R2- Overspending Get formal commitment from partners who have largely overspent that they will provide the ongoing support within the budget as foreseen in the DoW before the end of November 2011. The Commission received and accepted two statements from the overspending partners CSIRO and INAF indicating their commitment to the project on 1 Dec 2011 Both partners provided letters that described their historical partnerships with the EVN as well as their commitment to maintain their efforts to complete the necessary work associated with the project. Slide: 36 NEXPReS P2 Review – Brussels - 21 September 2012 WP 1- Management

37. R3- Testimonials (1 of 2) Close and fruitful links with end-users can be assumed but are not well documented in the deliverables. Some testimonials should be brought to the next review. The role and effectiveness of eVSAG should also be described in more detail in the deliverables or reports of the second period. The eVSAG meeting Nov 2011 highlighted the way in which the eVSAG brought together information and showcased the increasing use of e-VLBI by the community (presented by Tom Muxlow as chair of the EVN PC) ▫ There was a prominent NEXPReS WP7 Demo *and* how to adjust responses to ToO ▫ Additional talks covering: status of current e-VLBI sessions, e-VLBI proposal rates, and e-VLBI science results Slide: 37 NEXPReS P2 Review – Brussels - 21 September 2012 WP 1- Management

38. R3- Testimonials (2 of 2) Muxlow has confirmed that an EVN Users Session will be incorporated into the next EVN Symposium ▫ October 2012, Bordeaux, France ▫ Muxlow supported the session and desire to “solicit some feedback and testimonials with regard to e-VLBI” ▫ …and took a personal interest, stating “I will ensure that a discussion regarding e-VLBI is placed in the agenda “ The eVSAG is helping to organize a large conference “Locating Astrophysical Transients” in May 2012 ▫ The week-long meeting is being held in Leiden, the Netherlands ▫ The goal: promote (e-)VLBI and the (e-)EVN to the broader astronomical community engaging the community to provide new ideas on how transient research should be done with the EVN ▫ Further to identify “hot topics” in various fields (supernovae, GRB, optical transients, TeV sources etc.), and how the needs of this broader community could be best served Slide: 38 NEXPReS P2 Review – Brussels - 21 September 2012 WP 1- Management

39. R4- WP7 workplan WP 7 must revise its workplan in order to recover the accumulated 2-month delay during the next 24 months. New workplan should be submitted by the end of 2011. In December 2011, WP7 Leader Kettenis produced a revised workplan addressing the delays in the workplan The Commission approved the document in January 2012 Slide: 39 NEXPReS P2 Review – Brussels - 21 September 2012 WP 1- Management

40. R5- Publication Rate (1 of 2) WP5 and WP1 (as management) should pay more attention on publication rate in support of an adequate dissemination of the results. Some actions to accelerate the publication pace of the final user, the radio-astronomer, using e-VLBI should be studied and proposed in a revised workplan by the end of Q1, 2012. During conversations at the end of Nov 2011 and beginning of Dec 2011, it was agreed that NEXPReS (or the EVN) has little control over publication pace ▫ Most of the advances that come out of WP5 will not result in publishable papers until multiple telescopes can support 4 Gbps observations ▫ The geodetic users are turning around publications more quickly because they have the ability to implement their changes directly into observations Slide: 40 NEXPReS P2 Review – Brussels - 21 September 2012 WP 1- Management

41. R5- Publication Rate (2 of 2) We took these issues seriously and integrated the concerns into the revised D5.2 deliverables as appropriate We note that e-VLBI based papers are asked to cite e-VLBI, JIVE and NEXPReS Slide: 41 NEXPReS P2 Review – Brussels - 21 September 2012 WP 1- Management

42. R6- WP8 & User Requirements The future deliverables in WP8 must describe explicitly in which way the technology choices are influenced by the user requirements identified (e.g. D7.01 and D7.02). Across WPs ▫ WP6 – BoD links provided for testing (OSO, UMAN) ▫ WP7 – Actively involved (e.g. in WP8 face-to-face meetings) developers of WP7 software correlation  To bring in WP7 user requirements  To maximize WP7 ↔ WP8 software compatibility With the VLBI user community ▫ Fulfilling the need for handling telescope data rate increases 4Gbps (near-term with dBBC) and beyond Slide: 42 NEXPReS P2 Review – Brussels - 21 September 2012 WP 1- Management

43. Recommendations from P1 Review Revise the content of Deliverable D5.2 to include real metrics to measure reliability, availability as perceived by the user, scalability, robustness as planned in the DoW (see the comments on progress with WP5 in the review report) and resubmit before the end of November 2011.

WP5 and WP 1 (as management) should pay more attention on publication rate in support of an adequate dissemination of the results.
