Simple Spectral Access use cases, by Mike Fitzpatrick fitz at noao.edu Thu Jun 19 13:30:52 PDT 2003 Previous message: Simple Spectral Access use cases Next message: UCD for SIAP Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] Forgive me for not just lumping these all as "various NOAO spectral libraries" but I though the different storage formats and associated data tables would provide for some interesting use cases. Something like a cutout service might be appropriate for some of the data, the challenging thing for us however to put all these into an SSA is simply the variety of local data access methods required. Cheers, -Mike Data Providers (e.g., data centers, archives) Provider Name: NOAO Collection: High Resolution Atlas of Arcturus Spectra - 0.92-5.36 microns Characteristics: 310 ASCII tables of wavenumber vs flux Storage Format: Text tables Available online: ftp://ftp.noao.edu/catalogs/arcturusatlas/ir Comments: Tables contain three flux values (arcturus spectrum, telluric spectrum and ratio) for both summer and winter observations.

Wallace and Hinkle 1996 ApJS 107 312. ----------------------------------------------------------------------------- Provider Name: NOAO Collection: Library of Medium Resolution Infrared Stellar Spectra Characteristics: Spectra of 147 MK standard stars covering the H, J, and K bands. The spectra have been corrected for telluric absorp- tion and are at a resolution of 3000. Linear WCS Storage Format: FITS images Available online: ftp://ftp.noao.edu/catalogs/medresIR Comments: Spectra are from five papers by (variously) Wallace, Hinkle, Meyer, Edwards, and Strom. ----------------------------------------------------------------------------- Provider Name: NOAO Collection: Coude Feed Spectral Library Characteristics: Spectra of 684 stars observed with the Coudi Feed telescope and spectrograph at KPNO. The spectra cover the ranges 3820 - 4500 E and 4780 - 5460 E at a resolution of 1.8 A FWHM (~60 km/sec). Linear WCS Storage Format: FITS images Available online: ftp://ftp.noao.edu/catalogs/coudelib Comments: Library of stellar spectra covering a wide variety of spectral types, luminosity classes, and metallicities. Sample selection was based almost entirely on the availabil- ity of atmospheric parameters for the stars. Leitherer, C. et al. 1996 PASP, 108, 996. ----------------------------------------------------------------------------- Provider Name: NOAO Collection: Library of Stellar Spectra Characteristics: 160 1-D spectra covering 3510-7430 A at a resolution of 1.4 A/pix, linear WCS Storage Format: FITS images Available online: ftp://ftp.noao.edu/catalogs/jacobyetal.spec/ Comments: Library of stellar spectra covering entire range of spectral types.
