[Radioig] Call for contributions for the April interop

[Mark Lacy]

Dear radio interest group members,

The IVOA Northern Spring interop meeting is coming next month (April 
25-29). We will hold a session of our interest group during this meeting.

We are calling for contributions on implementation of services for 
interferometry or single dish data as well as for some feedback on the 
ObsCore extension proposal (typically a 10-15min presentation, but we 
can be flexible).

A reminder that the group pages can be found at : 
https://wiki.ivoa.net/twiki/bin/view/IVOA/IvoaRadio, with our services 
implementation review note at: 
https://www.ivoa.net/documents/Notes/RadioVOImp/index.html and our 
Obscore extension proposal at: 
https://github.com/ivoa/ObsCoreExtensionForVisibilityData

Regards

Mark Lacy & Francois Bonnarel
