I began to study statistics with the notion that statistics is the study of information (retrieval) and a part of information is uncertainty which is taken for granted in our random world. ... The statistician?s task is to articulate the scientist?s uncertainties in the language of probability, and then to compute with the numbers found : cited from The Philosophy of Statistics by Dennis V.

Statistics can be found for profiles or planes, specified using the axes keyword. The data can be converted to Kelvin, by using 'options=tb' and the beam keyword. ...

Next: Catalog Construction Up: Observations and Analysis Previous: Source Detections . ... It was assumed that the highest signal gives the most likely position of the source. ... Comparing the summed map with the maps from the individual energy ranges, the one which produced the smallest error box was chosen to represent the source position, as long as was greater than 4, a level chosen to reflect a reasonable degree of confidence in the detection. ...

... The GW from coalescing compact binaries composed of NS and BH are the best understood of all astrophysical GW sources. A conservative lower limit to the event rate of galactic binary neutron star coalescence of about 1 per 100000 year follows from double pulsar   statistics studies (Narayan et al. ... In Figure  47 we show the rates of coalescence of binary WD and NS in a model elliptical galaxy   consisting of stars, depending on time elapsed since the (assumed instantaneous) star formation. ...
