Members

name type mult description
complianceLevel ComplianceLevel The category indicating the level to which this instance complies with the SSA standard. Allowed values are 'query', 'minimal', and 'full'. See definitions of allowed values for details.
dataSource DataSource 1 or more The category specifying where the data originally came from. Allowed values are 'survey', 'pointed', 'custom', 'theory', 'artificial'
creationType CreationType 1 or more The category that describes the process used to produce the dataset. Typically this describes only the processing performed by the data service, but it could describe some additional earlier processing as well, e.g., if data is partially precomputed. Allowed values are 'archival', 'cutout', 'filtered', 'mosaic', 'projection', 'spectralExtraction', 'catalogExtraction'
supportedFrame ivoa:string 1 or more Identifiers of spatial reference frames that can be used in the POS parameter. The identifiers must be taken from the vocabulary http://www.ivoa.net/rdf/refframe. At least one recognized value must be listed when the service supports POS. With SSA v1.1, ICRS must be supported in that case; thus, this list must include at least this value.
maxSearchRadius ivoa:real optional The largest search radius, in degrees, that will be accepted by the service without returning an error condition. Not providing this element or specifying a value of 180 indicates that there is no restriction. Not providing a value is the prefered way to indicate that there is no restriction.
maxRecords ivoa:integer optional The hard limit on the largest number of records that the query operation will return in a single response. Not providing this value means that there is no effective limit. This does not refer to the total number of spectra in the archive but rather maximum number of records the service is capable of returning. A limit that is greater than the number of spectra available in the archive is equivalent to their being no effective limit. (See RM, Hanisch 2007.)
defaultMaxRecords ivoa:integer optional The largest number of records that the service will return when the MAXREC parameter not specified in the query input. Not providing a value means that the hard limit implied by maxRecords will be the default limit.
maxAperture ivoa:real optional The largest aperture that can be supported upon request via the APERTURE input parameter by a service that supports the spectral extraction creation method. A value of 180 or not providing a value means there is no theoretical limit. Not providing a value is the preferred way to indicate that there is no limit.
maxFileSize ivoa:integer optional The maximum spectrum file size in bytes that will be returned. Not providing a value indicates that there is no effective limit the size of files that can be returned. This is primarily relevant when spectra are created on the fly (see creationType). If the service provides access to static spectra, this should only be specified if there are spectra in the archive that can be searched for but not returned because they are too big.
testQuery Query optional a set of query parameters that is expected to produce at least one matched record which can be used to test the service.
