A new version is available.
The VizieR service is now hosted by CDS domain (cds.unistra.fr). It includes a new global positional search, based on the IVOA MOCS standard.
The domain "u-strasbg.fr" is obsoleted by the CDS domain "cds.unistra.fr".
Please, modify your configuration to the new domain.
The implementation used the mocset/moccli tools developped by FX.Pineau (CDS)
MOCS is currently available for the indexation only ans is used for query like https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-c=M1
the last version fixed also the "list of contraint" capability.
