   Simple Spectral Access Use Cases

    # Data Providers (e.g., data centers, archives)

       - Data provider name: INTA/LAEFF

       - Spectral data collections from this source: INES (IUE Newly-Extracted
   Spectra)

       - Characteristics of data (number of spectra, size, irregularly sampled,
         nonsampled (as in HE/UV) multiple flux arrays, variance arrays, etc.)

          + Total number of spectra: 110000
          + Total number of objects: 9500
          + Satellite lifetime: 18.6 years (Jan 1978 - Sep 1996)
          + Wavelength range: 1850-3350 angstroms (Long wavelength
spectrographs)
                           1150-1980 angstroms (Short wavelength spectrograph)
          + Data type:

               * Concatenated high-dispersion echelle 1-D spectra: 35000
spectra.
                 Size: 350Kbytes. Dispersion: 0.2 Angstroms. Non-linear
sampling.

               * Rebinned high-dispersion 1-D spectra (rebinned onto low
dispersion                       wavelength scale): 35000 spectra. Size:
18Kbytes. Linear sampling:
                         --> Long wavelength: 562 pixels @ 2.669 angstroms/pixel
                         --> Short wavelength: 495 pixels @ 1.676
angstroms/pixel

               * Low-dispersion 1-D spectra: 75000 spectra. Size: 18Kbytes.
                  Dispersion: 6 angstroms. Linear sampling:
                         --> Long wavelength: 562 pixels @ 2.669 angstroms/pixel
                         --> Short wavelength: 495 pixels @ 1.676
angstroms/pixel

               * Low-dispersion 2-D spectra: 68000 spectra. Size: 250Kbytes


     - Current data storage format:

               * Concatenated high-disp., rebinned high-disp., low-disp: FITS
binary                     tables. Each binary table contains four columns:
wavelength, absolute                 flux, associated error flux and quality
flag.

               * Low-dispersion 2-D spectra: FITS images.

     - Is the data available online? YES. http://ines.laeff.esa.es/ines/
