MWA Archive & VO Overview - Greg Sleap

NL: Q: Data staging always an achiles heel? Thoughts about a different way?
A: There is a cache, but still not directly accessable. Metrics out of the system such that you get an idea how long staging takes; typically 15 minutes.

BC: Q: Distance to sun, moon, jupiter?  How to find observations close to these sources (instead of avoid them).
A: Look for small number of degrees in the relevant columns.

Visualization for data cubes using SODA, as a preparation for the SKA archive - Ixaka Labadie , J.Garrido

JC: Q Evaluation of visualization tools; talked to teams?
A: Not really; did investgate the tools themselves.

FB: Q: When you query the services go from DataLink to SODA and then to your service or differently ?
A: Need to further discuss.

JS: Q: Separate service for cut-out operations or integrated in SODA?
 A: SODA service implements all the operations.

4D (spatial-temporal-spectral) radio data in the VO - B Cecconi et al

MD: Q: Can the zooing and panning be done with SODA?
A: Autoplot requires a time axis, so if SODA can provide cutouts with a time access then, in principle, yes?

Accessing data from the VLA Sky Survey via the VO - Mark Lacy

JJK: Q: SODA, are you thinking about binning or striding in addition to stacking?
A: Not in the SODA but some science application that does this on the SODA results.

FB: Q: Will you produce and .expose moment maps ?
A: No real line emission in the cubes; contiinuum data at the moment. Could be done in the future

Access from visualisation tools to SKA science images and cubes stored in a rucio DataLake through IVOA discovery and access services - F.Bonnarel

GS: Q: Test data from LOFAR, ASKAP, MeerKAT, etc. Any data from SKA-Low size?
A: Below, but this will come in the future. Used simulated data from data challenges.

Discussion

Q: Instrument-specific parameters? 
ML: UV characterization is probably preferred?
GS: Working antennas? Or antennas scheduled in the observations? Probably not so useful?
MD: Appeal: Don't think about what your particular instrument can do. Think about cross-instrument parameters. 
VXG UV characterization user stories.
FB: MK already made the comment about the user sceario behind.
ML: Multifrequency synthesis.
