- pyvo.dal.linesearch(baseurl, wavelength, **keywords)¶
- submit a simple SLA query that requests spectral lines within a wavelength range - 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. 
- **keywords
- additional parameters can be given via arbitrary case insensitive keyword arguments. Where there is overlap with the parameters set by the other arguments to this function, these keywords will override. 
 
- Returns:
- SLAResults
- a container holding a table of matching spectral lines 
 
- Raises:
