SLAQuery¶
- class pyvo.dal.SLAQuery(baseurl, wavelength=None, *, request='queryData', session=None)[source]¶
- Bases: - DALQuery- a class for preparing a query to an SLA service. Query constraints are added via its service type-specific methods. The various execute() functions will submit the query and return the results. - The base URL for the query, which controls where the query will be sent when one of the execute functions is called, is typically set at construction time; however, it can be updated later via the - baseurlto send a configured query to another service.- In addition to the search constraint attributes described below, search parameters can be set generically by name via the dict semantics. - The typical function for submitting the query is - execute(); however, alternate execute functions provide the response in different forms, allowing the caller to take greater control of the result processing.- initialize the query object with a baseurl and the given parameters - Parameters:
- baseurlstr
- the base URL for the SLA service 
- wavelengthQuantityclass or sequence of two floats
- the bandwidth range the observations belong to. assuming meters if unit is not specified. 
- sessionobject
- optional session to use for network requests 
 
 - Attributes Summary - the type of service operation which is being performed - the frequency/wavelength range the observations belong to. - Methods Summary - execute()- submit the query and return the results as a SLAResults instance - Attributes Documentation - request¶
- the type of service operation which is being performed 
 - wavelength¶
- the frequency/wavelength range the observations belong to. 
 - Methods Documentation - execute()[source]¶
- submit the query and return the results as a SLAResults instance - Raises:
- DALServiceError
- for errors connecting to or communicating with the service 
- DALQueryError
- for errors either in the input query syntax or other user errors detected by the service 
- DALFormatError
- for errors parsing the VOTable response
