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. ...

... While there is practically no detector noise present at energies above , X-ray data below are considerably contaminated by noise events, which become more and more dominant towards the lowest transmitted energies (Fig. ... Investigations of 40 hours of in-orbit calibration data with the filter wheel closed, taken over a period of more than two years, showed that the noise properties vary with position and energy, but are fairly stable in time for most areas on the detector. ...
