Corrected a typo about temperature distribution of BHB stars in Set I and Set II Readme files. The peak of BHB morphology is at log Teff = 4.3 instead of 4.05. Don't need, of course, to correct the models.
Added the effective magnitudes (and colors) in the Johnson, Gunn, and Washington photometric systems for the whole SSP library (see the new Set V data). These magnitudes directly deal with the Tonry-Schneider surface-brightness fluctuation theory (e.g. Buzzoni 1993, 2005).
Added the monochromatic effective number of stellar contributors for the whole SSP library. The quantity has been discussed in Buzzoni (1993) and Cerviño et al. (2002), and deals with entropy and statistical fluctuations of SSP photometric properties (Buzzoni 2005). See the new Set IV data.
Added the Hamilton (1985) Δ4000 narrow-band index to the whole SSP library. This index is a measure of the 4000 Å Balmer break alternative to the Δ index of Brodie & Hanes (1986) (see below). See and update the Set III data.
Added the Brodie & Hanes (1986) Δ narrow-band index to the whole SSP library. This index is a measure of the 4000 Å Balmer break. See and update the Set III data.
Added Gunn (griz) and Washington (CMT1T2) photometry to the whole SSP library (654 models in total). See Set Ib.
Fixed a bug in the 6 Gyr RHB models for Z = 0.10 (super metal rich). Colors and SED incorrectly nested in Set Ia/II (Lick indices and other quantities in Set III ok).
Completed and extended the set of Lick+IR indices for the full SSP grid (654 models in total). Synthetic indices include Mg2, Mgb, Hß, Fe5015, Fe5270, Fe5335, CO (2μ) and H2O (2μ) according both to Buzzoni's et al. and Worthey's et al. fitting functions.
Fixed a bug in the IHB library of SSP models. Please update (only the IHB subset at solar metallicity, Z=0.017)
Added CO, H2O & Lick (Hß, Mg2, Fe52, Fe53) synthetic indices to the RHB library of SSP models. [Work in progress to complete Set III for the whole library -- Updated on March 01, 2004]
Added Johnson H photometry to the whole SSP library.
Fixed a bug in the 2 Gyr model display (at all metallicities). Colors and model summary in Sets I/II ok in the original form but numerical display of the SED in Set II was incorrect.
