... The standard science quicklook processing produces over a dozen sky maps at each downlink, and these maps are automatically searched for potential transient point sources. ... We have found that a heuristic modification of a formula derived by Li & Ma (1983) provides reasonably accurate estimates of p -values for point source detections even for very low p -value detections. ... Case 1u. The most straightforward approach uses the signal , where . ... To get a p -value, use . ...

... This task takes an event list and makes an image in which the value in each pixel is proportional to the variability with respect to time of the flux of events which fall within that pixel. The task cycles through all the events in the list which fall within the spatial extent of the image; for each of these events, a value of the Kolmogorov-Smirnov statistic is calculated. ... Note the implication that pixels having zero variability are not zero-valued in the output image. ...

Proceedings of the Particle Physics and Early Universe Conference (PPEUC). For this paper: postscript PPEUC CMB index 1 Introduction .. ... A new statistic is discussed, designed to detect isolated coherent step-like discontinuities produced by cosmic strings present at late times. ... The statistical variable considered is the Sample Mean Difference (SMD) between large neighbouring sectors of CMB maps, separated by straight lines in two dimensional maps and points in one dimensional maps. ...

... 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. ...
