[Janet Evans]

Folks,

Just a reminder … the HEIG Neutrino meeting is today ..

> You can find four neutrino use cases in our KM3NeT fork of the ObsCore note here: https://github.com/KM3NeT/HighEnergyObsCoreExt/blob/1ee1f68d16ae312e20dc664f6718ca6f5408e056/UseCases.tex#L266 <https://www.google.com/url?q=https://github.com/KM3NeT/HighEnergyObsCoreExt/blob/1ee1f68d16ae312e20dc664f6718ca6f5408e056/UseCases.tex%23L266&source=gmail-imap&ust=1774608042000000&usg=AOvVaw2wWI2OLOVWSvKFtHX9BGtu>
> They cover querying an existing dataset from ANTARES, combining IRFs from CTA and KM3NeT (a use case where we have the IRFs, but they are not yet available through the VO), finding neutrinos from all available experiments for a given point source, and estimating the neutrino flux from an extended region. For the queries listed there, these only represent rough guesses, and are basis for discussion.

> KM3NeT VO services

> The technical setup for the implementation of the pilot is the DaCHS server at vo.km3net.de <https://www.google.com/url?q=http://vo.km3net.de&source=gmail-imap&ust=1774608042000000&usg=AOvVaw1-7Atz8XwWLdwSLmCCiEMi> and the dataverse instance holding auxiliary data like IRFs at opendata.km3net.de <https://www.google.com/url?q=https://opendata.km3net.de/&source=gmail-imap&ust=1774608042000000&usg=AOvVaw2OC7oJB4b_Qx-M1WkQj8ND>. For the implementation of the use cases, we are currently stuck with the problem that our DaCHS version is quite outdated and we have to upgrade first and move to a new server and containerize DaCHS before applying the changes required for the use cases. For the DaCHS inclined, you can find a (yet non-functional) resource descriptor for the ANTARES data here <https://www.google.com/url?q=https://git.km3net.de/open-data/voserver/-/blob/obscore/examples/Antares2017/nu.rd&source=gmail-imap&ust=1774608042000000&usg=AOvVaw0GzZGcQx3QTrpd4Ii3Z8kG>.

> As I am not sure how to proceed with the further implementation and change requests from the neutrino side, I think it would be good if we could focus the meeting mostly on the organizational part - how we interact in the implementation of the use cases, how this goes together with the ucd discussions and other current processes around the note - then we might perhaps manage to stay within the one hour ;)
