utype for STC region in SIAP query response

Thu Sep 1 02:16:35 PDT 2011

Hi Thomas,
    To complete my answer to Markus
     we could have something like
    
    <FIELD name="fov" unit="deg" xtype="STC-s" datatype="char" 
arraysize="*" utype="sia:Char.SpatialAxis.Coverage.Support.Area" >
    
       I think something like this can be proposed (if not yet the case) 
in SIA2...
       this will be consistent with ObsTap... and could also be included 
in the next version of SSA et al.

       For current SIA services, maybe we could have a short 
recommendation or note to propose using
the same as an additional field in the SIA1 Query response
Cheers
François
