... 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. ...

... There are many pitfalls in these kind of comparisons, which are described in great detail in the papers I have used to compare my impact on the field. In the first comparison I use the method described by Pijpers (2006, Astronomy Geophysics, 47, 6.17) , where he compares the total normalized citation rate per paper (i.e., the number of citations of a paper divided by the number of authors) to the total number of papers for different authors in the field of space research. ... 1st year paper . ...

Next: Combining Bias Frames Up: Preparing Your Calibration Previous: Input and Output . Except for summing the frames together, combining frames may require correcting for variations between the frames due to different exposure times, sky backgrounds, extinctions, and positions. ... The input frames are combined by applying a sigma clipping algorithm at each pixel. ... The input frames are combined with a variant of the sigma clipping algorithm which works well with only a few frames. ...

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. ...

... 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. ...

Statistics from S. Pesci and P. Mazza logbook. I began my visual hunting program in 1991, after some ten years of variable star observing and deep sky. My patrol galaxies were some one hundred circumpolar galaxies, which were suveryed with a 45cm home made Dobsonian. ... These are checked on average 10-15 times a year, during 35 to 45 nights (numbers depend much on weather), mostly on weekends and holidays. Since 1995 Piero Mazza has joined my search with his 40cm home made telescope. ...
