... rgsspectrum creates an OGIP-compliant spectrum of counts for a single RGS exposure. ... background-corrected source spectrum . ... Note that although the spatial selection region for the background spectrum is not source-specific, the energy selection region is source-specific, and for this reason the background spectrum is technically source-specific. ... The above description of the BACKSCAL column applies only to Spectroscopy mode data; in HTR mode this column has nothing to do with exposure. ...

... In spite of the good potential possibilities, some of the station "Dnepr" design characteristics did not allow us to apply the usual special IS radar measurement methods. ... Thus for IS signal measurements at the "Dnepr" station, we have developed special methods for recording and processing IS signals in order to determine plasma ionospheric parameters. ...

... When I display the weight map generated for my final drizzled image (or any of the single drizzled images as well), there seem to be representations of the objects in my science image. ... Most likely you need to refine the parameters that are set during the driz_cr step which detects cosmic rays in each of your science frames. ... I've calculated refined offsets between my science images but when I supply MultiDrizzle with the delta shifts the final image is not aligned properly. ...

Next: Gravitational Wave Background from Previous: Galactic Gravitational Wave Background . ... It is intuitively clear that at frequencies above the critical ones for our Galaxy, one will detect rare bright jerks produced by coalescing white dwarfs   (at a rate of 1 per 100 year) and NS (at a rate of 1 per - year) in our Galaxy, against a background of the extragalactic stochastic GW. ... Firstly we consider GWB from close individual galaxies, and then will discuss overall extragalactic GWB. ...

Disastrous earthquakes happen 100 to 200 times a year. ... There is a chance that the data of ionospheric plasma observations hold an answer to the latter question. Satellites and ground-based facilities may detect earthquake precursors in the ionosphere a few hours or days before the main shock. ... ULF "Hz"-oscillations have been recorded several hours before the main shock in a narrow magnetic field tube (40...100 km along the satellite trajectory) conjugated with epicenter of the earthquake. ...
