Overview

You can access this service using:

This service is not published. This can mean that it was deemed too unimportant, for internal use only, or is just a helper for a published service. Equally likely, however, it is under development, abandoned in development or otherwise unfinished. Exercise caution.

Other services provided on the underlying data include:

Input Fields

The following fields are available to provide input to the service (with some renderers, some of these fields may be unavailable):

NameTable Head DescriptionUnitUCD
mime Type MIME type of the file served N/A N/A
ssa_dateObs Date Obs. Midpoint of exposure d time.epoch
ssa_location Location ICRS location of aperture center deg pos.eq
ssa_targname Object Somewhat cleaned name of the target object as given in the file. The names should either be SIMBAD-resolvable or give a reference for the source. Some names we could not make sense of are marked with a tilda (~); any help figuring out what they are is appreciated. N/A meta.id;src

Default Output Fields

The following fields are contained in the output by default. More fields may be available for selection; these would be given below in the VOTable output fields.

ssa_specstart Band start Lower value of spectral coordinate m em.wl;stat.min
ssa_targname Object Common name of object observed. N/A meta.id;src

VOTable Output Fields

The following fields are available in VOTable output. The verbosity level is a number intended to represent the relative importance of the field on a scale of 1 to 30. The services take a VERB argument. A field is included in the output if their verbosity level is less or equal VERB*10.
