declination The angular distance above (positive) or below (negative) the celestial equator.
In (7), [[sigma].sup.i.sub.t-1] refers to the angular distance of the ith particle with respect to direction angle of the vehicle.
For this algorithm, the angular distances are arranged in an ascending order as guide star characteristic catalogue, thus the time for looking up in the catalogue is reduced.
The DOAs to estimate are [v.sub.1] = -30[degrees] and [v.sub.2] = -15[degrees] in Figures 7(a)(b) and so the angular distance between the two considered DOAs is such to be bigger of HPBW parameter.
It is thus only possible to compute the azimuth [phi] of arrival or departure of the rays in this plane and defined as the horizontal angular distance from the tunnel axis z to the direction of the rays.
The resulting database is equivalent to peppering the entire sky with sources separated by an angular distance of two full moons," she said.
Initially, due to the long simulation durations in Matlab, tests were done only for the first half of an year, with a temporary distance of 10 days and a latitude angular distance of 11[degrees].
Greatest elongation east of the Sun--an angular distance of 20[degrees]--is reached on April 26, when Mercury will set 2h12m after sunset; an hour after sunset, the magnitude +0.4 innermost planet will stand about 9[degrees] above the horizon at azimuth 296[degrees] in the NNW, an easy naked eye target perhaps also presenting some wide-field photographic possibilities.
The solstice occurs the instant the sun's position in the sky is at its greatest angular distance on the other side of the equatorial plane from the observer's hemisphere, which for us, of course, is the Northern Hemisphere.
The angular distance between each hole is 40[degrees] (360 / 9 = 40).
Similarly, Earth orbits every 365.25636 days, travelling an angular distance of 0.9856[degrees] per day (Figure 2).
The factors were target field (right; upper; left and lower), cue-target angular distance (45, 90, 135, 180, 225 (-135), 270 (-90) or 315 (-45)) and ISI (100 or 800 ms).
USE THE CORRECT DISTANCE The distance from your perch in the tree to the animal (angular distance) is farther than the distance from the base of the tree to the animal (horizontal distance).Yet your bow is probably sighted for the horizontal distance.
However, if the angular distance c is close to zero or 180[degrees], the theorem leads to the computation of arccos x in the neighborhood of x = [+ or -] 1.
