To construct two-dimension distribution of minor planets user should specify elements/ parameters/ function that will be plotted as abscissas and ordinates. In three-dimension case one should add to them the element plotted on Z axis. ... Though you may choose elements plotted along different axes at will, often there is good reason to plot such elements as a, n, or n" along X axis (two-dimension distributions) and to plot them along Y axis in three-dimension case. ...

The beam pattern and the polarization characteristics . of the radio telescope RATAN-600 . The Mueller matrix elements was computed via formulas [1]: . ... The BP were computed by the aperture method, proceeding from the fild distribution in the aperture of the primary mirror. The components of the main and cross-polarization components of the electric field in the vertical aperture of the primary mirror was computed in Frenel diffraction approximation. ...

... A response matrix is a discrete representation of a given instrument's response to incoming photons. ... This presentation is a preliminary report on MKRMF, a new tool developed by the Chandra X-ray Science Center (CXC), to calculate RMFs appropriate for the variety of science instruments on-board Chandra (Wise 1998). ... These external redistribution functions are stored using a new FITS format developed by the CXC for encapsulating functions. ... axes file : . ... list file : . ... CXC RMF Format ...

... Figure: A dark current CCD exposure with cosmic ray events which are removed with non--linear filters. ... Figure shows a CCD dark current exposure with cosmic ray events. ... Figure: Removal of cosmic ray events on a CCD spectral exposure with different techniques: (A) original, (B) median filter, (C) recursive filter and (D) stack comparison. ... For comparison with non--linear filter techniques, Figure D shows removal of cosmic ray events from the spectral frame discussed above. ...

We have designed the laboratory model of static Fourier spectrometer for onboard usage for spectral study of atmosphere and ionosphere. The gain of model is to simulate onboard FS which will not have any moving elements (all its optical elements will be mounted at fused quartz monolithic construction), to compare experimental results with theoretical estimations and to measure MTF of CCD array. ... This fact connected with low frequency response of CCD array due to small format of it. ...

... Archives . ... It refers to the spread in the measured energy of an incoming photon, and even astronomers often stumble over what it is and what it contains. ... The R edistribution M atrix F ile (RMF) is, at its most basic, a description of how the detector responds to incoming photons. ... The process of measuring the energy introduces a measurement error, which is encoded as the probability that incoming photons at energy E are read out in detector channels i . ...

... The distributions of orbits eccenttricities and of angular momenta for the halo stars and the old disk population are considered. The distributions have gaps separating the halo from the disk and dividing the halo population into three groups. ... Рассмотрены распределения звезд гало и старого населения диска по величине эксцентриситета орбит и угового момента. Распределения имеют провалы, отделяющие гало от диска и делящие населения гало на три группы. ...

Next: Mission Element Points-of-Contact . Previous: Mission Operations Data Transfer . ... Each mission element should ensure that their contact information remains current and notify the RSOG of any changes. ... Non-RSOG mission elements will also use the "dit" list to notify the RSOG (and all other mission elements) of unexpected events that may impact operations elsewhere, e.g., if a tracking station discovers that the spacecraft is in an unexpected configuration. ...

Collection of the orbital elements | ... The errors of the spacecraft motion extrapolation outside the measuring time interval were estimated by using the comparison of SC positions calclulated by the forward integration ( extrapolation method) and backward integration ( interpolation methods). ... The character of these time shift of the ascending nodes ( D Tn) corresponds to the orbiting period errors, which arise during SC motion extrapolation outside the measuring intervals. ... INTERBALL mission ...

... Beamwidth defines the field of view 2. ... Large diameter = high sensitivity = small beamwidth 3 To calculate the radiation pattern : Compute field in focal plane from surface currents excited by the incoming wavefront. ... Feed Legs (quadrupod on the AT antennas) plane wave shadows (radiation which does not reach the main reflector) spherical wave shadows (radiation blocked between the main and the sub-reflector) 6 Surface Errors н Ruze formula Let be the rms surface error. ...
