Waveband¶
- class pyvo.registry.Waveband(*bands)[source]¶
- Bases: - Constraint- A constraint on messenger particles. - This builds a constraint against rr.resource.waveband, i.e., a verbal indication of the messenger particle, coming from the IVOA vocabulary http://www.ivoa.net/rdf/messenger. - The - pyvo.registry.Spectralconstraint enables selections by particle energy, but few resources actually give the necessary metadata (in 2021).- Multiple wavebands can be given (and are effectively combined with OR). - Parameters:
- *bandsstrings
- One or more of the terms given in http://www.ivoa.net/rdf/messenger. The constraint matches when a resource declares at least one of the messengers listed.
