HUT Quick Look Spectral Atlases for Astro-1 and Astro-2

By clicking on the items below, you can see examples of HUT spectra of various types of astronomical objects. Each spectrum is labeled and contains a brief caption describing the object being observed. Below the examples are listings that provide summary information and access to quick look spectra from all objects observed during the Astro-1 (Dec. 1990) and Astro-2 (Mar. 1995) missions, ordered by object name.

• Active Galactic Nucleus Example Spectrum
• Cataclysmic Variable Example Spectrum
• Supernova Remnant Example Spectrum
• Planetary Nebula Example Spectrum

• Astro-1 Spectral Atlas Listing
• Astro-2 Spectral Atlas Listing

Click on either of these items to get a listing of all objects observed during the Astro-1 and Astro-2 missions. Clicking on highlighted items in these lists will show you the spectral data in Postscript format. These can be downloaded for future reference if desired. For Astro-1 data, total and "night only" spectra, which are generally of higher quality, are available. For Astro-2 data, day, night, and total observations are available with separate clicks.

PLEASE NOTE: These data are provided by the HUT team only as a convenience to the community, and are intended primarily to provide insight into the data quality available. However, they have been produced by a standardized process and may not reflect the best that can be done with individualized processing. Much more information, including the raw data, "day" and "night" sections of all observation separately, 5-minute time slices, etc., are all available from the archived data sets through the National Space Science Data Center (NSSDC) at NASA/Goddard Space Flight Center.
