Next: Caverns in Binary Systems Up: Ejectors in Massive Binary Previous: The Number of Ejectors . In the very first years after the discovery of radiopulsars, it became clear that for some reason they avoid forming binary systems. ... Illarionov and Sunyaev (1975)[ 76 ] noted the fact that coherent radiowaves with a wavelength longer than 75 cm, which make it possible to observe most of the radiopulsars, are absorbed effectively in the stellar wind of a normal star. ...

Data access in GIPSY is done through a set of routines collectively known under the name `` GDS '' (GIPSY Data System). ... A set consists of one or two files: the descriptor file and the image file. ... In GIPSY there are kinds of coordinates: . ... To retrieve a descriptor item, given its name and level, the GDS reading routines start looking at the specified level and if it is not found there, higher levels are tried. ... Every GDS routine has an integer error argument, which often is optional. ...

The need of source separation methods in astronomy has led various adaptations of decomposition methods available. ... I rarely come up with a paper which gathered and summarized component separation methods applicable to astronomical data. In that regards, the following paper seems useful to overview methods of reducing dimensionality for astronomers. [arxiv:0805.0269] . ... Chandra Blog . ...

As a result, a common magnitude scale (contour lines on the maps above, or color scale on Fig.1) will poorly display the short-duration events in a signal. Normalizing each line of the map (fixed duration) so it has unit variance (in effect dividing the energy map by the mean energy spectrum) at each duration restores more details of small-scale activity (Fig. ...
