Specific Intensity Spectra and Limb Darkening

We just made specific intensity spectra (a.k.a. the ‘full radiation field’) for all models in the base grid (i.e. [alpha/Fe]=0) available for download. They span the wavelength range from 500 to 26000 Angstrom with a sampling of 1 Angstrom. We provide the spectra for 78 different values for the angle mu.

Furthermore we’ve convolved those specific intensity spectra with commonly used filters to be used for limb darkening applications. The results are also available for download. In case you need different filters, please send us their response curves.

Wrong reference for STELIB

Unfortunately there has been an error in the published paper. The reference that we give for the STELIB is obviously wrong, the correct one is this:

STELIB: A library of stellar spectra at R ~ 2000

Le Borgne, J.-F.; Bruzual, G.; Pelló, R.; Lançon, A.; Rocca-Volmerange, B.; 
 Sanahuja, B.; Schaerer, D.; Soubiran, C.; Vílchez-Gómez, R.,
 2003, A&A 402, 433

ADS: 2003A&A...402..433L

The astro-ph version has already been corrected, but it was too late for the A&A publication…


First update

We have just uploaded an update to the server that consists of two parts:

  1. The missing interpolated spectra, 325 in total. A full list can be found here. All these spectra contain a FITS keyword “INTERPOL” with the value “T” for easy identification.
  2. Since the start of this website, 1365 additional spectra have been calculated successfully that we also uploaded now. See this list for details.

The new spectra are available individually in high resolution and have been added to the archives with the medium resolution spectra.
