... The procedure of radiometer signal integration can be considered as a sort of reducing dimension of the initial sampling space, where the samples are the result of analog-to-digital conversion. ... The probability distribution of the signal and spikes is completely known. ... The quality of the considered algorithm could be also illustrated by Figure 2 . ... One could see the considered adaptive algorithm is preferable even by low degree of compression, because all spikes have been depressed. ...

The FSP3 event includes those parts of the magnetic conjugations between any couple of four considered spacecraft, which satisfied to the FSP1 or to the FSP2 criterion. ... The value of the relative geocentric angular distance between magnetic field line's footprints is considered during FSP3 situation selection. The mentioned angular distance value less then 5 deg is used as a criterion of the magnetic conjugation. ... for the first SC the red color and the first line are used, . ...

XMM-Newton Science Analysis System . ... This task returns the following statistical information for each column in the list specified by the parameter column , present in the table specified by the parameter table : . The minimum value . The maximum value . The mean average . The root mean squared . ... The results are written to the standard output as well as the text file specified by the parameter resultfile .

Next: Simulated Results with Up: Assessment of Methods Used Previous: Introduction . ... Then one has to use regularized inversion methods in order to obtain approximate and sensible solutions. ... All these methods contain a free parameter which is the so-called regularization parameter; in the case of method ( ) this is a smoothing of the higher spatial frequencies; for the methods ( ) - ( ), it is the number of iterations. ... In the case of method ( ) the iteration scheme is given by . ...

The database contains references to the papers, data files and links to the Internet resources related to measurements and calculations of the optical constants in the wavelength interval from X-rays to radio domain. ... References to some useful books and reviews on the subject (e.g. the classical handbooks edited by E.D.Palik) and links to Internet collections of optical constants and personal WWW pages with related software were also placed in the database. You have arrived at our welcome page. ...

The Doppler shift is the effect of sound increasing or decreasing in pitch as an object moves towards or away from you. ... Light works the same way, except light is shifted to redder colours when an object is moving away, and to blue colours when an object is travelling towards us. ... Almost every object he observed had its light stretched to redder colours, indicating essentially everything in the Universe was moving away from us. ... So the Hubble constant tells us how old the Universe is. ...

Modern AstroStatistics has emerged as a new field in recent times, informed by a Bayesian foundation, utilizing powerful computational tools like MCMC, and applied to diverse analysis and inference problems in Astronomy. ... The goal of our Special Session is to review current practices, highlight modern techniques, and explore how the transition into the realm of Big Data Astronomy can be facilitated. ... Big Computing in Astronomy: Perspectives and Challenges . ...

... They are concerned with Attitude Control System of the spacecraft, satellite visibility from tracking stations, limits on the satellite autonomous operations during the orbit, and needs for auxiliary operations with the spacecraft. ... Among the operational constraints the most important one is the number of programmed slews per orbit, which determines the maximum number of radio sources to be observed during one orbit. ... System temperature (K) . ... Progress of the RadioAstron Project in Pictures...
