declination The angular distance above (positive) or below (negative) the celestial equator.
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.
Further simulations with latitudes between 84[degrees]-89[degrees] N and a latitude angular distance of 1[degrees] (Fig.
The angular distance between each hole is 40[degrees] (360 / 9 = 40).
Our main findings were: (a) MRT was maximal when C- T distance was 0[grados] and minimal when C-T distance was 180[grados] and (b) besides an angular distance effect, there is a meridian effect.
If you have practiced and sighted-in by taking range readings along the angular distance straight to the target from your treestand, make sure you do the same thing when hunting.
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.
In conditions of heavy fog -- which will be our focus here -- only the rear lights of the vehicle in front are visible, and the distance to that vehicle is perceived on the basis of the visible characteristics of the car's lights: their angular size, their luminance, and the angular distance between them (if there are two).
The two right spherical triangles and one spherical triangle of Fig 5 allow the calculation of the angular distance from the roll axis and the target (j):
Even though the starlit bodies are separated by an angular distance of just 70 arcseconds--a minuscule fraction of the width of the full moon as seen from Earth--the near-infrared sensor was so tiny that it could only record the infrared light from one galaxy at a time.
Horizontal positions are usually specified in one of two ways: 1) Latitude and Longitude, which specify the angular distance from a reference point on the earth's surface taking into account the fact that the surface is curved; and 2) Rectangular or Cartesian coordinates, which specify the horizontal distances at right angles from a reference point and which ignore the curvature of the earth's surface.
The Helen Keller National Center Act of 1992 defines an individual who is deaf-blind as an individual "who has a central visual acuity of 20/200 or less in the better eye with corrective lenses, or a field defect such that the peripheral diameter of visual field subtends an angular distance no greater than 20 degrees, or a progressive visualloss having a prognosis leading to one or both of these conditions; who has a chronic hearing impairment so severe that most speech cannot be understood with optimum amplification, or a progressive hearing loss having a prognosis leading to this condition; and for whom the combination of impairments .
If B's distance from the earth can be determined, the increase in the angular distance between A and B can be determined and, using the known time between the observations, B's transverse velocity can be calculated.
For fluorescence, pattern recognition factors encompassed spectral area, peak positions and angular distance between spectra.
Jupiter will move close to the moon on Wednesday (March 7) at 10am, when the angular distance between them will be four degrees and Qatar residents will be able to watch the phenomenon with naked eyes over south eastern horizon of Doha sky from 10:33am on Tuesday to 5:52am on Wednesday, QCH Astronomer Dr Beshir Marzouk said.
