Научная панорама ? arxiv:0710.3165 Черная дыра с массой 15.65 солнечных . ... arxiv:0710.3165 Черная дыра с массой 15.65 солнечных в затменной двойной системе в близкой спиральной галактике М33 (A 15.65 solar mass black hole in an eclipsing binary in the nearby spiral galaxy Messier 33) . ... Авторы сообщают о том, что оценка массы черной дыры в одной из внегалактических тесных двойных систем оказалось довольно высокой - около 16 масс Солнца. ...

The paper presents the 'Neptune-ME' information display system (IDS) as a spaceman console (SC) of the descent module of the 'Soyuz -TMA' piloted transport spaceship, and the integrated console (IC) of manual control loop for module equipment in the Russian segment of the 'Alpha' international space station. ... to control spaceship systems; . ... An integrated control console (ICC) which is hardware and software compatible with a IBM PC, is suggested as a basic console for the manual control loop. ...

... Left: A POSSM plot of the uncalibrated spectrum of DA 193 at 1.66 GHz on a baseline Bear Lakes to Noto. ... The phase slope as a function of frequency is clear evidence for a small delay error in the correlator model. Right: The same data as shown on the left, but corrected for a delay error and a residual fringe rate. ... Left: A VPLOT plot of the uncalibrated amplitude (upper frame) and uncalibrated phase (lower frame) as a function of time for the source DA 193 on a baseline HartRAO to Noto. ...

Mobile Device to Digitize the photographic plates: first results Grosheva E.A., Izmailov I.S., Khrutskaya E.V. Pulkovo Astronomical Observatory, Russian Academy of Sciences, St. Petersburg, Russia Abstract -- The first results of astrometrical reduction for 40 Saturn and Pluto's plates are presented. ... This method of digitization and astrometric reduction of photographic plates using a digital camera is developed due to the problem of plate archive transportation to the high-tech measuring machines. ...

... SHORT TERM PREDICTION OF POWER SOLAR FLARES FROM SSRT DATA . The algorithm for short term prediction of powerful solar flares, based on SSRT data, includes microwave emission characteristics in total and polarized flux, the structure of active region (AR) magnetic field at the photospheric level, and H a patrol data. ... During this period, 7 AR's crossed the solar disk, in which 20 flares of importance ? ... Data on AR's and magnetic fields were received from the Sayan observatory by teletype. ...

... Калибровка снимка - это удаление из него паразитной информации, которая включает в себя: темновой шум, горячие пиксели, шум считывания (ток смещения), а также тени от пыли на матрице и оптике. Для калибровки снимка нужно подготовить снимки с паразитной, т.е. нежелательной информацией. В первую очередь нам нужно получить мастер-кадр шума считывания (ток смещения), на западе снимок шума считывания называют Bias или Offset . ... Уровень темнового шума сильно зависит от температуры матрицы. ...
