The lines and circles in the equatorial plane
map onto circles on the sphere.
Lying on a plane perpendicular to the equatorial plane
, the analyzer can be considered (from a geometrical point of view) as a mirror for the x-rays, thus actual calculations of the reflection follow easily from Eq.
Note that the X, Y, Z (capitals) are symmetry-axes of the Earth, where the Y-axis coincides with the polar axis and X, Z are (random) axes in the equatorial plane
The (hk0) rings orient preferentially in the equatorial plane
(the vertical direction in the photographs) and are partially obscured on the top side by the beam stop.
Previously, Cassini was orbiting in the equatorial plane
of the planet, and the imaging team's images of the polar vortex between late March and mid-May were taken from a location over Titan's equator.
Substituting the explicit expressions for the components of the metric tensor in the equatorial plane
of the spherical body yields
Adrastea and Metis orbit Jupiter almost exactly in the equatorial plane
They discovered that if Uranus had been hit when still surrounded by a protoplanetary disk-the material from which the moons would form-then the disk would have reformed into a fat doughnut shape around the new, highly-tilted equatorial plane
The first and second plies are made up of substantially parallel metallic reinforcing cords embedded in a rubber composition that are inclined with respect to the equatorial plane
of the tire, and the cords of the first ply are inclined with respect to the cords of the second ply.
For orbits confined to the equatorial plane
of a homogenous oblate spheroidal mass [1, 8]; [eta] [equivalent to] 0 (or d[eta] [equivalent to] 0) and substituting the explicit expressions for the components of metric tensor in the equatorial plane
GOES satellites orbit the equatorial plane
of the Earth at a speed matching the Earth's rotation.
A year ago, from its unique vantage point high above the south pole, Ulysses scanned the sun's equatorial plane
as far as Earth's orbit and recorded at radio wavelengths the pinwheel structure predicted by theory.
