... A lightweight stick with two balls of equal weight at its end obviously has its CG in the middle. When one ball is twice the weight of the other, the CG divides the distance between them by a ratio 1:2, in a way that makes it closer to the heavier mass ( see figure ). ... Even though the balls are separate, one can speak of their common center of gravity, on the line connecting their centers, 1/3 of the distance from the center of the heavier ball. ...

The Big Bang has no center. It is not an explosion radiating from a point. ... This shell has both an outer and an inner edge, and these can be used to locate the position of the explosion. But in the Big Bang there is no edge. The Figure below shows a galaxy A and the velocities measured by observers on A: . ... You might think that by backtracking the velocity vectors you can locate the center of the Big Bang (and it is at A) but this is not the case! ... FAQ | Tutorial : Part 1 | ...

... The amount of energy encircled by an aperture used for stellar photometry will depend on both the aperture size, and also on any variations in the PSF with field position, time, etc. ... The differences in photometric magnitude between apertures with various radii (i.e. aperture corrections), and their mean and standard deviations for the F555W filter, are presented in Table 5.5 . ... Variations in the PSF with field position will, of course, cause a position dependence in the aperture corrections. ...

. 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.

Describes how spatial region boundaries are handled. The golden rule for spatial region filtering was first enunciated by Leon VanSpeybroeck in 1986: . ... With this in mind, the rules for determining whether a boundary image pixel or table row are assigned to a region are defined below. For image filtering, pixels whose center is inside the boundary are included. ... That is, an row is inside the boundary without regard to its integerized pixel value. ...
