Dear App members,<br>
<br>
A <b>new version of the MocServer has been released </b>Monday 21
March (<i>recall: the MOC Server has been deployed at CDS to
retrieve as fast as possible (a few ms) the list of astronomical
data sets (catalogs, surveys, ...) having at least one observation
in a specifical sky region. The default result is a data set ID
list. It is notably used by Aladin Desktop v9 for continously
update the list of available HiPS overlapping the current user
view.)</i><br>
<br>
Presently the MocServer contains <b>15 958 MOCs</b> + associated
metadata coming from VizieR, Simbad, and HiPS servers.<br>
<br>
The main improvement of this version concerns the extension of the
query language (simpler and better boolean query support, wildcard
support even on metadata key words...). Also, the VizieR tables MOC
accuracy have been increased for providing MOCs at order 11
(<=> 1.7arcmin resolution).<br>
<br>
This service will be maintained in <b>operational level</b> by CDS.
Feel free to use it if you wish.<br>
