Assigned ID: 832 ----- Attempting Submission 1 (Fri Feb 24 22:32:10 GMT 2012) ----- We propose to derive high level science products from the STIS snapshot program data which constitutes the Next Generation Spectral Library. The NGSL covers four metallicities, very low ([Fe/H] < -1.5), low (-1.5 < [Fe/H] < -0.5), near-solar (-0.3 < [Fe/H] < 0.1), and super-solar ([Fe/H] > 0.2), well-sampling the entire HR-diagram in each bin. Our main goal is to develop code to use the NGSL as a basis for interpolating spectra of arbitrary atmospheric parameters in Teff -- log(g) -- Z. A secondary goal is extension of the library spectra to the near-IR and to echelle resolution, mainly using data already obtained for this purpose. Both of these goals will increase the value of the NGSL database for use in modeling the integrated light of galaxies and clusters. We will make the results available to the community via MAST and a public website. UNRESOLVED STELLAR POPULATIONS AND GALAXY STRUCTURE 12 Medium false 0.0 0.0 false false false false SUPPORTED
