[Mireille LOUYS]

Dear all,
I agree with the addition of this term and also with these descriptions .

Thanks , Mireille

>>   New Term: spatial-profile
>>   Action: Addition
>>   Label: Spatial Profile
>>   Description: An observable obtained along a one-dimensional path.
>>   Relationships: narrower than #spatially-resolved-dataset
>>   Used-in: TBD
>>
>>   Rationale:
>>   Spatial profiles are commonly used in single-dish radio observations,
>>   where a cross of about five beams centered on the target object is
>>   scanned for computing flux backgrounds or pointing
>>   corrections.  Other profiles used in radio astronomy scan over elevation
>>   to create opacity corrections.
>>
>>   Another case for spatial-profile would be when a planetary probe takes
>>   measurements along its flight path.  Both sorts of data products clearly
>>   need discovery modes of their own because they have analysis modes
>>   rather distinct from other data product types.  Whether the different
>>   sorts of profiles need further separation remains to be seen in usage.
>>
>> I would suggest that discussions on the concept itself should happen
>> on the Radio IG's mailing list.  Any feedback is most welcome.
