Abstract. The Pulkovo spectrophotometric catalog was published in Baltic Astronomy Vol.5 No.4 (1996). Here we present a supplement of the catalog containing the flux distribution data for 77 stars in the wavelength range from 320 nm to 735 nm. Actually, this is a direct continuation of Table 6 of the catalog.

A "toy model" of molecular evolution of sequences in copolymers is proposed and implemented using a molecular-dynamics-based algorithm. The model involves coupling of conformation-dependent and sequence-dependent properties. It is shown that this model allows the realization of two main possibilities: ascending and descending branches of evolution (in terms of information content of a sequence), depending on the interaction parameters shaping the conformation of a polymer globule. The problem of adequate description of information complexity of copolymer sequences is studied. It is shown that Shannon's entropy or compressibility of a sequence gives preference to random sequences and therefore cannot be applied for this purpose. On the other hand, the Jensen-Shannon divergence measure turns out to give the description of information complexity which corresponds to our intuitive expectations. In particular, this characteristic can adequately describe two branches of evolution mentioned above, exhibiting a singularity on the boundary of these regimes.

Abstract.A spectrophotometric catalog is presented, combining results of numerous observations made by Pulkovo astronomers at different observing sites. The catalog consists of three parts: the first contains the data for 602 stars in the spectral range of 320-735 nm with a resolution of 5 nm, the second one contains 285 stars in the spectral range of 500-1080 nm with a resolution of 10 nm and the third one contains 278 stars combined from the preceding catalogs in the spectral range of 320-1080 nm with a resolution of 10 nm. The data are presented in absolute energy units W/m 2 m, with a step of 2.5 nm and with an accuracy not lower than 1.5-2.0 %.
