... Глава 4. ... Торможение небесных тел . ... Это относится и к небесным телам Солнечной системы. ... На основании этого можно сделать вывод, что торможению подвергаются и все небесные тела Солнечной системы, как и других звездно-планетных систем, при наступлении галактических зим, когда Солнечная система проходит в своем обращении вокруг центра Галактики через спиральные рукава, а также через плоскость Галактики между рукавами или через газово-пылевые облака, встретившиеся на периферии Галактики. ...

... Basic algorithms for the production of stellar photometry from CCD observations are described and reviewed. ... The problem of doing accurate stellar photometry with calibrated charge-coupled device (CCD) data amounts to that of condensing the intensity values of hundreds, thousands, or even millions of picture elements (pixels) into a list containing the magnitude and position of each star on the CCD image. ... Center an aperture of N A pixels on the star. ... PIXEL.LT.PEAKMAX)) THEN BINGO = .TRUE....

... xmmtrack . ... xmmtrack is an interactive IDL application that visualizes the orbit and attitude data in an ODF in the form of a 3-D animation sequence. The presented scenery includes an astronomically accurate simulation of the Earth-Sun system plus the actual and predicted trajectory of the XMM satellite on its path around the Earth. ... Please note: XMM's orbit is highly time variable and the predicted orbit will significantly deviate from the actual trajectory if the reference epochs differ. ...
