pyvo.dal.ssa.search(url, pos, size, format='all', **keywords)[source]¶

submit a simple SSA query that requests spectra overlapping a

Parameters:

url : str

the base URL for the SSA service

pos : 2-element sequence of floats

a 2-element seqence giving the ICRS RA and DEC in decimal degrees

size : float

a floating point number giving the diameter of the circular region in decimal degrees around pos in which to search for spectra.

format : str

the spectral format(s) of interest. “all” (default) indicates all available formats; “graphic” indicates graphical images (e.g. jpeg, png, gif; not FITS); “metadata” indicates that no images should be returned–only an empty table with complete metadata.

**keywords:

additional parameters can be given via arbitrary keyword arguments. These can be either standard parameters (with names drown from the SSAQuery.std_parameters list) or paramters custom to the service. Where there is overlap with the parameters set by the other arguments to this function, these keywords will override.

Returns:

SSAResults

a container holding a table of matching spectrum records

Raises:

DALServiceError

for errors connecting to or communicating with the service

DALQueryError

if the service responds with an error, including a query syntax error.
