Vocabulary: http://www.ivoa.net/rdf/product-type Author: Vincenzo Galluzzi Date: 2023-11-13 New Term: spatial-profile Action: Addition Label: Spatial Profile Description: An observable obtained along a one-dimensional spatial 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.
