. Next: Initial velocity Up: Space and velocity distributions Previous: Space and velocity distributions . Following Paczynsky (1990), we assume initial space distribution of young neutron stars to be varying exponentially with distance from the Galactic center and from the Galactic plane, that is probability distribution for young neutron star positions can be written in the form . with kpc, and pc.

... Moving the sample locations to achieve the desired warping will result in an irregularly sampled image plane. These irregularly spaced samples will then be brought back to regularly spaced positions, hence warping the image. ... The sampled impulse response, , is a function of the sample positions, . ... Allowing the sum to go outside the image boundaries ( or ) includes some ``anchor'' samples outside the image, which tends to stabilize the solution trajectory when is minimized. ...

... R P is the perigalactic radius and R a , the apogalactic radius. Z max is the maximum deviation of the star from the Galactic plane. THe dotted curve shows the position of the Galactic plane. The hatched horizontal band shows schematically the band in Z , where the probability of that location of the star was calculated. The vertical band shows the width of the column in which we reconstruct the star distribution in Z . ... next figure | previous figure . ...

Next: Deconvolution with CLEAN Up: Image Deconvolution Previous: Image Deconvolution . ... The convolution theorem states that the Fourier transform of the sampled distribution (the dirty image, ) is equal to the convolution of the Fourier transform of the true source visibility distribution (the true image, I ) and the Fourier transform of the sampling function (the dirty beam, ): . where indicates convolution, and indicates the Fourier transform. ...

... Next: Cheating Poisson: A Up: Statistical Analysis Previous: Spatial Models and . ... The spatial distribution of stars in the Local Group dwarf irregular galaxy NGC 6822 has been studied, using recent positions and deep photometry for about 15,000 stars in the galaxy. Based on photometrical data, OB stars and red stars could be studied separately. Spatial statistical tools have been applied to the analysis of the spatial structure. ...

The weight and positions for the objects on the rotary floor were obtained from ecastro on nov03 and used to plot the weight distribution on the rotary floor. ... The figure shows the weight distribution by turret position. ... Fig 1 top: Each object on the floor is plotted with its weight vs its turret position. Fig 1 middle: The weight is averaged by turret position quadrant to show the imbalance in weight distribution. ... The turret position is that of the receiver or read off of the drawing. ...

A STUDY OF THE FRAGMENT DISPERSAL AND TRAJECTORY OF THE SAYH AL UHAYMIR 001 METEORITE SHOWER. ... We obtained hundreds of GPS find locations, analyzed the fragment distribution, and developed a model of the meteorite's trajectory. ... More than 2670 samples weighing more than 450 kg have been collected. ... Increasing fragment mass along track indicated a flight direction of 233o. The fragments' mass distribution was used to model the meteorite trajectory. ...

... For an input list of EBOXDETECT source locations, simultaneous maximum likelihood PSF fits to the source count distribution are performed in all energy bands of each EPIC telescope. A description of the main properties of the detection algorithm may be found in Cruddace, Hasinger, Schmitt (1988). ... Note, that =1 in the case of the individual energy band detection likelihoods listed in source table rows with ID_BAND 0 and is equal to the total number of energy bands in the ID_BAND=0 summary rows. ...
