  This is an introduction to the tabulated data base of stellar matter
properties calculated within the framework of the Statistical Model for
Supernova Matter (SMSM). The tables present thermodynamical characteristics and
nuclear abundances for 31 values of baryon density (10$^{-8}<\rho/\rho_0<$0.32,
$\rho_0$=0.15 fm$^{-3}$ is the normal nuclear matter density), 35 values of
temperature ($0.2<T<25$ MeV) and 28 values of electron-to-baryon ratio
($0.02<Y_e<0.56$). The properties of stellar matter in $\beta$-equilibrium are
also considered. The main ingredients of the SMSM are briefly outlined, and the
data structure and content of the tables are explained.
