    Dear all,<br>
    <br>
    to follow on propositions for chair and vice-chair as raised by
    Bruno, I think that, together with IVOA experts,  it would be good
    to associate someone with experience in at least one of the
    experiments. <br>
    To me Bruno is the right person with many "hats" (CTAO, VODF, some
    obscore knowledge...)<br>
    <br>
    Best regards,<br>
    Catherine<br>

      <p>Dear all,</p>
      <p>I might be travelling during this time slot, returning from the
        RICAP meeting. So I apologize for my absence....<br>
        I have put additional comments about the note on gitlab after a
        second reading. Otherwise, I could be present in Malta to
        support the group if needed, just let me know in order to book
        my travel in advance.</p>
      <p>As I could probably not be present during the next meeting, I
        give here my opinion about your important point about the C and
        the VC. I personally feel that Janet and Mathieu could be the
        leading tandem for our interest group, in the continuity of
        their animation/leading role they have had up to here, and
        offering a HE/VHE balanced tandem of IVOA experts.</p>
      <p>Otherwise, for information, in the continuity of our previous
        discussion about the link between the alerts and the HEIG, I
        heard during the Sept. Fermi symposium a presentation about AI
        usage to read GCN alerts. This appears to me like a headlong
        rush: by refusing to primary use machine-readable formats like
        VOEvent (that might need a refreshment to cover the new GW and
        HE use cases!), the use of very complicated tools having a high
        carbon footprint permits to transform a text into
        machine-readable information. This is a bit sad when formats
        exist and not used. This is why I personally think that the work
        into IVOA is very important.<br>
        AS consequence, the creation of the HEIG is for me a very urgent
        action that will serve the whole community, us of course in
        HE->UHE with photons and neutrinos, but also for the other
        astrophysics domain by offering a fresh vision on standards
        based on our daily science use cases and by proposing updated
        recommendations.  <br>
      </p>
      The best,<br>

        <div>Hi Mathieu/All,</div>
        <div><br>
        </div>
        I planned to send a similar suggestion to move the mtg.  The TCG
        and HEIG meeting ended up on the same day/time. 
        <div><br>
        </div>
        <div><b>Moving HEIG to ===>>>  Fri, Sep 27 @14:30 UTC
            works for me!!</b>
          <div>Folks, please let us know if this is a bad time and I
            will send a poll for an alternate if needed.</div>
          <div><br>
          </div>
          <div>With regard to the session, I sent the outline to this
            group and responded to 2 emails.  With no further
            discussion, I gave CSP the OK to pursue invitations.
             Hopefully that will happen in the next few days and we’ll
            have a program to discuss when we meet.  I consider this a
            JOINT session - HEIG/CSP - no one gorup is leading.</div>
          <div><br>
          </div>
          <div>My concern too is the state of the HEIG Note.   Please
            folks, if you have actions to pursue, please help out and
            let’s get that doc in good shape.</div>

          <div>We also need to discuss who will be Chair and V Chair of
            the group so we have a recommendation to the Exec.  This is
            one of their concerns … it’s often difficult for them to
            fill position and I believe it will help them out.  For an
            interest group, it will be best to be a scientist for at

                      Hi all,<br>
                      <br>
                      thanks Janet for the proposition, I see that you
                      reached interesting conclusions at the CSP meeting
                      yesterday, and that High Energy is accepted as one
                      of the priorities :-). As we agreed, it will be a
                      good exposition for the HE, particularly if it is
                      supported by CSP, and the session should focus on
                      scientific use cases and needs.<br>
                      <br>
                      My initial comment on the program is that there is
                      a mention of "X-ray and Gamma-ray", and then "Very
                      high energy", which is also gamma-ray. Or is it
                      another aspect of gamma-ray?<br>
                    </blockquote>
                    Maybe would be better as:<br>
                    <br>
                    - space telescopes : X-ray to GeV Gamma-rays<br>
                    - ground-based telescopes: >GeV Gamma-rays<br>
                    <br>
                    Since that is really where the difference in use
                    cases are. The latter would contain both IACTs (e.g.
                    CTAO) and WCTs (e.g SWGO/HAWC/LHASSO). Although
                    those also have quite different needs for the data
                    model, so that could even be split further into
                    "pointed instruments" (CTAO, HESS, etc) and
                    "wide-field instruments" (SWGO/HAWC/etc).<br>
                    <br>
                    <br>
                    <blockquote type="cite">There is a topic on
                      Gravitational Waves, but nothing on Neutrinos,
                      though we identified more commonalities with
                      Neutrinos observatories. Shouldn't we split this
                      contribution in 2 shorter presentations?<br>
                      <br>
                      The questions to ask to the speakers make me think
                      of what we asked for the workshops we organised 1
                      and 2 years ago. The first one was a
                      per-instrument overview (<a

                      and quite focused on event-lists and alerts. And
                      the second asked for presentation of science use
                      cases on high-energy data, in terms of data access
                      and analysis for different experiments (<a

                      It was more centered on a few observatories
                      (Chandra, HESS, XMM). Anyway, it was quite
                      interesting to highlight the specificities and
                      need of the HE domain in the VO.<br>

                      écrit :<br>
                      <blockquote type="cite">Dear HEIG Folks,<br>
                        <br>
                        Some movement since our meeting last Friday on
                        the Plenary session.<br>
                        <br>
                        At the Aug30 HEIG meeting, Francesca suggested
                        to work with the IVOA Committee for Science
                        Priorities (CSP) on a plenary session combining
                        High Energy and TDAMM.  We’re also coordinating
                        with the Time Domain IG.  With this approach we
                        have High Energy science talks covering the
                        various wavebands and ask the speakers to answer
                        a set of questions to cover topics of interest
                        in the IVOA and HEIG group.  At the end of the
                        session, we will plan a wrap-up talk by a HEIG
                        member summarizing the overlap with IVOA,
                        highlighting the HEIG Note we’ve been working
                        on, and making our ‘ask’ to become an IVOA
                        interest group. Does this sound good to folks??<br>
                        <br>
                        Here is an outline we were thinking for the
                        session:<br>
                            • 18+2 - X-ray and Gamma-ray<br>
                            • 18+2 - GW LVK and Einstein Telescopes<br>
                            • 18+2 - Very high energy<br>
                            • 18+2 - Alert Services<br>
                            • 10 minutes talk from HEIG representative
                        asking for the IG status<br>
                        <br>
                        We picked some people both in and out of the
                        HEIG group as speakers. It is a good list but
                        perhaps too early to share in an email group.
                         Ada and Francesca had good ideas and I provided
                        HEIG names.  Here are the questions we put
                        together to ask the speakers to address:<br>
                           o How does your project make their data
                        discoverable?  Are data from your project in the
                        IVOA registry?  Are there problems in the IVOA
                        Obscore definition preventing or limiting it?<br>
                           o What data products are used in your data
                        analysis and are they interoperable with data
                        from other projects?  Do you use a data model?<br>
                           o What do you use for an alert system?  Do
                        you use VOevent, and if not, can you address the
                        issues you see?<br>
                           o How do you coordinate follow up
                        observations currently?  Are the Observing plan
                        of your project/mission available externally and
                        is there coordination of your project/mission
                        among the HE projects?   Are you familiar with
                        the IVOA ObsLocTAP protocol and ObjObsSAP
                        working draft of the IVOA?<br>
                        <br>
                        Looking for feedback … especially if you have
                        strong feeling against this plan.  I think
                        personally it will be the session we need.
                         Given the 3 day meeting, combining with CSP
                        & Time Domain IG who are willing to help is
                        good too.  We’re looking to get invitations out
                        next week so folks can plan their travel.<br>
                        <br>
                        BTW, I wrote up the notes to out Aug 30 meeting.
                         Let me know if I missed you on the ‘attendee
                        list’ , if the actions are accurate, and if
                        there was something significant I missed in the
                        discussion.  <a
