A standard stellar library
Listed in IVOA Registry (Virtual Observatory)
The present library provides an extensive and homogeneous grid of low-resolution theoretical flux distributions for a large range of stellar parameters : Teff=50,000K to K, logg=5.50 to -1.02 and [M/H]=-5.0 to +1.0.
Description
The library has been constructed from different grids of blanketed stellar atmosphere models (Bessell et al. (1989A&AS...77....1B, 1991A&AS...89..335B), Fluks et al. (1994, Cat. <J/A+AS/105/311>), Kurucz (1995, priv. comm.), Allard & Hauschildt (1995ApJ...445..433A).
The models described in the accompanying paper (Lejeune et al. (1997A&AS..125..229L) are given here as part of a more extensive data set including M dwarf model spectra, which will be presented in a forthcoming paper (Lejeune et al., 1998, Cat. <J/A+AS/130/65>). A correction procedure has been applied to the theoretical energy in order to calibrate fluxes on empirical-temperature relations (see also Lejeune et al., 1998, Cat. <J/A+AS/130/65>).

The library is given here in its two versions : the first one (files *.ori) containing the "original" flux distributions -- as given by the original grids of atmosphere models --, but rebinned on a common wavelength scale (see also Leitherer et al. 1996PASP..108..996L) and the second one (files *.cor) which provides the "corrected" flux distributions. Each version of the library contains an ASCII file of models for each of the 19 values of the metallicity ([M/H]=-5.0, -4.5, -4.0, -3.5, -3.0, -2.5, -2.0, -1.5, -1.0, -0.5, -0.3, -0.2, -0.1, 0.0, +0.1, +0.2, +0.3, +0.5 and +1.0), named as lcbxxx.yyy, where xxx designates the metallicity (ex: 'm15' --> [M/H]=-1.5), and yyy identifies the library version.
For each model (out of the total of 8315 models), a flux spectrum is given for the (same) set of 1221 wavelength points covering the range 9.1 to 160000 nm, with a mean resolution of 10{AA} in the UV and 20{AA} in the visible. In addition to the 19 metallicity files, two individual files originating from the Kurucz (1991, in Precision Photometry: Astrophysics of the Galaxy, Davis Philip A.G., Upgren A.R. & Janes K.A. (eds.).
Schenectady, NY, L. Davis Press, Inc., 1991, pp. 27-44)) models are given, lcbsun.ori and lcbvega.ori, which provide theoretical flux distributions for the Sun and Vega respectively.
