... BTA and RATAN-600 are largest optical and radio telescopes in Russia. ... Antenna of RATAN radio telescope consist of 576-m circle of 895 elements (2 x 11.5 m), which could use as four independent sectors (225 elements) of that reflector (named: North, South, West and East). Four different feed-cabines (N1,2,3,5) with secondary mirrors could simulteniously collect radio emission from these four sectors and be used in programs of Continuum , Spectral and Solar observations. ...

The Arcetri Spectral Code (Landi and Landini 2002) allows to evaluate the spectrum of continuum and line radiation emitted by hot and optically thin plasmas in the spectral range 1-2000 Angstrom. The Code is composed by a large database of atomic data and transition probabilities for calculating spectral line emissivities and a suite of fortran programs able to evaluate free-free, free-bound and two-photon continuum radiation. ...
