1. Brief description: Yunnan-II models for SPs

Yunnan-II models provide the results of SPs with and without binary interactions (BIs) at three spectral resolutions. The results at 8~20Å, 0.3Å and 0.1Å are obtained by using BaSeL, HRES and BLUERED stellar spectra libraries, respectively. The intermediate-resolution (3Å, 2006.MNRAS.370.1181) ISEDs can be obtained by convolving high-resolution ISEDs with a Gaussian function.

Those results using BaSeL, HRES and BLUERED spectral libraries are referred to as Yunnan-II-BaSeL, Yunnan-II-HRES, Yunnan-II-BLUERED. For these results, the age coverage is the same while the metallicity and wavelength coverages are different (see the following table).

Han et al. (2007) presented the ISEDs of populations with the binary interactions of sdB. We have combined them into the Yunnan-II-BaSeL models for SPs with BIs. This set of models is called Yunnan-II-BaSeL-sdB (NOTE: this set of models only includes the results for SPs with BIs).

——Based on the Yunnan-II-BaSeL, Yunnan-II-HRES and Yunnan-II-BLUERED models, we give the ISEDs, stellar mass (M*), magnitudes (48), mass-to-light ratios (8, M/L) and Lick/IDS indices (25) for SPs with and without BIs.

ISED: at three resolutions (8-20Å, 0.3Å and 0.1Å);

Magnitudes and stellar mass: stellar mass, bolometric magnitude and other magnitudes (47 magnitudes, on Vega or AB systems). These magnitudes include GALEX (Fuv, Nuv), SDSS (u, g, r, i, z), Johnson (U, B, V, R, I), 2MASS (J, H, K) and HST-WFPC2 (f122m—f1042m, 32 filters) magnitudes;

Mass-to-light ratios: mass-to-light ratios for various light (only U, B, V, R, I, J, H and K);

Lick/IDS indices: two sets of results (obtained by empirical fitting functions [FF] or by direct computations [DC] from Yunnan-II-BLUERED ISEDs, which have been degraded to Lick resolution) are provided. 25 indices are included, including CN1, CN2, ..., HγF.

—— Based on the Yunnan-II-BaSeL-sdB models, we give the low-resolution ISEDs, stellar mass, magnitudes (48) and mass-to-light ratios (8) for SPs with BIs.
