The parameters of the unique solar complex at the RATAN-600 were enhanced. Determined by the unit's instrumental errors, the maximum accuracy of polarization measurements was reached on the panoramic spectrum analyzer PAS of the RATAN-600: 0.02-0.03% in the measurements over the entire solar disk, and 0.2-0.3% in the measurements of point sources. Automation of the complete cycle of solar observations with the RATAN-600 was finalized, with the daily multi-wavelength observational data outputs to the Internet via the SAO servers and SOHO satellite.
A coude-echelle spectrometer of high and very high resolution was designed
and manufactured for the 2-meter telescope (Terskol peak) with
the simultaneous spectrum registration in a wide wavelength range
