... 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 J, H and K bands are characterized by a bright background, such a background is mainly due to the emission of atmospheric lines and of thermal radiation. ... If the source cover a large fraction of the slit, spectra off-source must be observed to adequately sample the sky background. ... The on chip integration time (time spent in each position of the slit) must not exceed 40 seconds in J and H bands and 60 seconds in K band. ... We suggest a sequence of 10 for each elementary integration time. ...

... Typically, an observation specified by an observer cannot be directly executed by an observatory. Observation specifications need to be configured so that they can be used by other components of the observatory. This paper motivates the need for configuration tools and describes a software architecture which supports configuring astronomical observations. ...
