Dear all,

    A VOTABLE implementation of the characterisation data model is released in the CDS Aladin server / SIA Atlas mode ...

    This service can be accessed via General browsers such as NVO DATASCOPE.     (In the Datascope "RESOURCEs" query response page, look in the "Other" section of the Images Resources for the "Aladin" slot)

     For each Image in the SIA Atlas mode CS server (currently containing 2MASS, IRAS-IRIS and WENSS images) Two lines are available

   one with ucd= "VOX:Image_Format" name = "OriginalCoding" FIELD set to "image/fits"
  and one with ucd= "VOX:Image_Format" name = "OriginalCoding" FIELD set to "text/xml"

   Clicking on the latter (using the View or link buttons) you will get the full characterisation result for this observation in VOTABLE format...

    This implementation gives spatial , time, and spectral characterisation spatial is given up to level 3: the support is given by an stc polygon in sky coordinates.

    Time is given upto level 1
    Spectral band is given up to level 2.

    NO Flux/observable characterisation is given because the calibration is not well known!

    Preliminary versions of this service have been demonstrated in the Victoria and Moscow Interop Meetings

   What is planned in the followings days/weeks:

We are waiting for your comments

François and the characterisation team
