... We will consider the rms, (K), for observations with a receiver of system temperature, T , frequency resolution, per polarization, and total integration time per observing cycle, . ... For ``in-band'' frequency switching, the line under investigation is always in the observing band. ... Position Switching or ``Out-of-Band'' Frequency Switching: Here the line is only observed for one half of the time, with noise being present all of the time. ...

Orbit . ... The orbit of the RadioAstron provides four types of study: . rough images of radio sources with ultra-high angular resolution, using all baselines up to the radius of the apogee, that is much larger than Earth diameter; . ... high quality imaging of radio sources, with moderate resolution, by observing either with small projected base lines Earth-spacecraft, i.e. close to the orbital plane, or near the perigee. ... high accuracy orbit determination. ... Space Radio Telescope . ...

... December 21, 1997 . ... Advantages are briefly discussed of gaining in spectral resolution, which is accompanied by losses in signal level, as compared with the attempts to improve the accuracy of measurement of line parameters by means of rising the S/N ratio alone with increasing the exposure time. To partially solve the problem of observations of faint objects at the BTA a new design echelle spectrometer is proposed. high resolution spectroscopy . ...

About us . ... Telescopes . ... Apart from the 6-meter telescope BTA two small telescopes are operative at SAO: the 1-m and 0.6-m telescopes, both manufactured by Carl Zeiss, Jena, are located near the BTA. ... These telescopes are used for adjusting the equipment and techniques of observations used at the BTA. ... The observational time allocation and also a brief description of the equipment of the 1-m telescope, which is used either permanently or mainly on this telescope, are presented below. ...

... For observations we selected all Case galaxies in the zone = - from the Case lists III, IV, V, VIII, XI, XII and XIII which were classified in the Case survey by some indication on presense of [O III ] 4959,5007 emission lines (vs - very strong, s - strong, m - medium, w - weak, w? - weak?) and which had not been observed yet. ... Аdditionally nine Markarian galaxies in the same sky region were observed in hope to have better completeness in picking up all probable BCGs. ...
