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.
NOTE: Note the spectra shown are from old HUT data (pre-2013 version), but they are still representative.
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 time-tagged photon lists, "night-only" spectra, TV guider images, etc.,
are all available from the archived data sets available through the Search Forms.
