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.1997A&AS..125..229Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/125/229CatalogResearchIsServedByTAP VizieR generic servicerelated-toVI/39 : Model Atmospheres (Kurucz, 1979)VI/78 : Theoretical Stellar Flux Spectra for F- to K-type Stars (Buser+ 1992)J/A+AS/105/311 : M giants spectra and photometry (Fluks+, 1994)J/A+AS/130/65 : A standard stellar library.
