Meeting Agenda

• Meeting notes in BOLD
• Prototype status:
  • Make prototype specs available to HEIG
    • A few general actions for folks writing prototypes
      • Make prototype specs available to HEIG
      • Make sample HE data sets available when possible to the community that are available as a result of the obscore extension
  • CXC prototype accessing data products from the Chandra Source Catalog (Ian/Janet)
    • summarized current spec and active work by CXC developer
    • 37 different data products
      • half are defined with the different attributes; running fast, should be finished soon
      • the existing clients are not perfectly in line with these new products; TopCat should handle that
    • will make spec and data available when the details have settled down in iterations with the prototype.
    • How hard would it be to adapt the CSC prototype to XMM SSC or ERASS?? - answer for APtak
  • ObsParis prototype on access to HESS data using the HE obscore extension (Mathieu)
    • HESS public data release of event list (soon the CTAO Science Data Challenge event-list release)
    • MS displayed a table with the HEIG obscore extension and their TAP server; not yet event bundle and separated IRFs
    • Discussion about how MOCs fit in: TMOC is desirable, in contrary to SMOC (the s_region is enough)
    • What about Event bundle? Discussion about Antares data given that they need specific entries for IRFs. JE took an action to setup a meeting on Antares.
• Settle on the author list for the HEIG note, then discuss next steps once the update is made (All)
  • Discussed author list and made a plan.
  • JE will send pointer to doc to current author list and HEIG group asking the following: 1) Are there any others who should be added - reply to BK/JE; 2) For those currently listed - Please give your OK to be an author. 3) Let me know if you don't want to be on the list. Before it goes out, JE will check other Standards notes for the correct format for author names (include email and institution for example).
• Vocabularies: The VEPs strategy for the HE Obscore extension (Mireille/Baptiste)
  • Mireille has defined new UCDs in a Note from a meeting in Paris; she has propositions for new UCDs to add and will circulate via email for discussion/feedback. Once in a mostly good place, we will call a meeting for near complete review.
• Expectations between now and June Interop (All) … here’s the start of a list for discussion
  • Complete author list; update note
  • Session on Neutrino data
  • Settle the VEPs
  • Distribute note to IVOA; make any tweaks
  • Settle the Prototypes
  • Request an endorsed note from TCG
  • June IVOA meeting ... the TCG Endorsed note/IVOA meeting should happen on the same timescale
  • Post IVOA - share Doc to WG along with Radio & Timing and support WG efforts on Obscore
• AOB
