The second issue encountered was slight subpixel offsets in the relative astrometry between the filter mosaics. To account for these, we determined the sky coordinates for a number of moderately bright stars in the field by fitting their point spread functions with two-dimensional Gaussians. We ...

Known fully as the Global Positioning System (GPS), it is composed of dozens of satellites, which provide geographic coordinates for various earthly features. Originally put into orbit by the U.S. Department of Defense, they've been available for civilian benefit since the 1980s, and since ...

and technology valuation has moved towards "monetization". Goheal has been tracking hundreds of M&A and restructuring projects for a long time, and found that more and more companies have begun to layout around the triple coordinates of "technical content + policy friendliness + risk hedging", an...
The other coordinates can be found in the same way. Answer and Explanation:1 From the above, The {eq}x\ -\ coordinate {/eq} of the centre of mass is equal to {eq}\displaystyle X_c\ =\ \frac{m\ \times\ 0\ +\ m\ \times\ L\ +\......
