embargo -- Date the data will become/became public owner -- Owner of the data ssa_aperture -- Angular diameter of aperture ssa_bandpass -- Bandpass (i.e., rough spectral location) of this dataset; this should be the most appropriate term from the values of VODataService vs:Waveband. ssa_binSize -- Bin size in wavelength ssa_cdate -- Processing/Creation date ssa_collection -- A short handle naming the collection this spectrum belongs to. ssa_creationtype -- Process used to produce the data (archival, cutout, filtered, mosaic, projection, spectralExtraction, or catalogExtraction) ssa_creator -- Creator of the datasets included here. ssa_creatorDID -- Dataset identifier assigned by the creator ssa_cversion -- Creator assigned version for this dataset (will be incremented when this particular item is changed). ssa_datasource -- Method of generation for the data (one of survey, pointed, theory, custom, artificial). ssa_dstype -- Type of data (spectrum, time series, etc) ssa_fluxStatError -- Statistical error in flux ssa_fluxSysError -- Systematic error in flux ssa_fluxcalib -- Type of flux calibration (ABSOLUTE, CALIBRATED, RELATIVE, NORMALIZED, or UNCALIBRATED). ssa_length -- Number of points in the spectrum ssa_pdate -- Date last published. ssa_pubDID -- Dataset identifier assigned by the publisher ssa_publisher -- Publisher of the datasets included here. ssa_redshift -- Redshift of target object ssa_snr -- Signal-to-noise ratio estimated for this dataset ssa_speccalib -- Type of wavelength calibration ssa_specres -- Resolution on the spectral axis ssa_spectStatError -- Statistical error in wavelength ssa_spectSysError -- Systematic error in wavelength ssa_targclass -- Object class (star, QSO,...; use Simbad object classification http://simbad.u-strasbg.fr/simbad/sim-display?data=otypes if at all possible) ssa_targetpos -- Equatorial (ICRS) position of the target object. ssa_timeExt -- Exposure duration
