          SEE Level 3 OVERVIEW:  
          The Solar EUV Experiment (SEE) is comprised of two science components: 
* the EUV Grating Spectrograph (EGS) component covers the wavelength range from approximately 26 to 190 nm
* the X-Ray Photometer System (XPS) component covers the wavelength range from approximately 0.5 to 34 nm 

Level 3 data has flares removed, is useful for long-term climatological study.

    <Caveats>SEE Level 3 data files contain one daily averaged solar irradiance spectrum in 1 nm intervals extracted 

          from the EGS Level 2 and XPS Level 2 data products. Shortward of 27 nm, a solar model is scaled to match the 
          XPS broadband data. SEE Level 3 data files also contain 38 emission lines extracted from EGS Level 2 spectra, 
          and the XPS Level 2 diode irradiances.

For normal operations, SEE observes the Sun for about 3 minutes every orbit (97 minutes), which usually gives 14-15 
measurements per day. The SEE Level 3 data are time averaged over the entire day, after applying corrections for atmospheric 
absorption, degradation, flare removal, and to 1 AU.
