The primary goal of these experiments was to measure the angular scale of the first acoustic peak, for which COBE did not have sufficient resolution.

Although WMAP provided very accurate measurements of the great angular-scale fluctuations in the CMB ( structures about as broad in the sky as the moon ), it did not have the angular resolution to measure the smaller scale fluctuations which had been observed by former ground-based interferometers.

In object space, the corresponding angular resolution is

where λ is the wavelength of the waves that are focused for imaging, D the entrance pupil diameter of the imaging system, in the same units, and the angular resolution δ is in radians.

Herschel discovered that unfilled telescope apertures can be used to obtain high angular resolution, something which became the essential basis for interferometric imaging in astronomy ( in particular Aperture Masking Interferometry and hypertelescopes ).

X-ray astrometry becomes a serious concern that results in ever greater demands for finer angular resolution and spectral radiance.

The angular resolution of the telescope is an important factor in the detection of visual binaries, and as better angular resolutions are applied to binary star observations increasing number of visual binaries will be detected.

To achieve higher angular resolution, some infrared telescopes are combined to form astronomical interferometers.

When used together with adaptive optics, infrared interferometers, such as two 10 meter telescopes at Keck Observatory or the four 8. 2 meter telescopes that make up the Very Large Telescope Interferometer, can achieve high angular resolution.

* 2002 — The Cosmic Background Imager ( CBI ) in Chile obtained images of the cosmic microwave background radiation with the highest angular resolution of 4 arc minutes.

As a result, the angular resolution of space telescopes such as the Hubble Space Telescope is often much smaller than a ground-based telescope with a similar aperture.

This type of instrument was later improved, with more carefully scribed discs providing better angular resolution, as well as through mounting telescopes with reticles for more-precise sighting atop the disc ( see theodolite ).

Before the launch of X-ray-observing satellites, such as the Chandra X-ray Observatory, X-ray observations generally had quite low angular resolution, but when the Moon passes in front of the nebula, its position is very accurately known, and so the variations in the nebula's brightness can be used to create maps of X-ray emission.

The use of interferometry allows radio astronomy to achieve high angular resolution, as the resolving power of an interferometer is set by the distance between its components, rather than the size of its components.

Also since angular resolution is a function of the diameter of the " objective " in proportion to the wavelength of the electromagnetic radiation being observed, radio telescopes have to be much larger in comparison to their optical counterparts.

With an angular resolution of 0. 5 arcsecond ( 2. 4 µrad ), it has a thousand times better resolution tnan the first orbiting X-ray telescopes.

This aliasing is visible in images such as posters with lenticular printing: if they have low angular resolution, then as one moves past them, say from left-to-right, the 2D image does not initially change ( so it appears to move left ), then as one moves to the next angular image, the image suddenly changes ( so it jumps right ) – and the frequency and amplitude of this side-to-side movement corresponds to the angular resolution of the image ( and, for frequency, the speed of the viewer's lateral movement ), which is the angular aliasing of the 4D light field.

The angular width the secondary reflector subtends at the feed horn is typically 10 °-15 °, as opposed to 120 °-180 ° the main reflector subtends in a front-fed dish.

Alternative meanings include " angular, having corners ", " swollen ", or " possessing a dish or receptacle ".

The USALS calculates the dish angular position given by the dish lon / lat and the position of the satellite in geostationary orbit.

Traditional kayaks encompass three types: Baidarkas, from the Alaskan & Aleutian seas, the oldest design, whose rounded shape and numerous chines give them an almost Blimp-like appearance ; West Greenland kayaks, with fewer chines and a more angular shape, with gunwales rising to a point at the bow and stern ; and East Greenland kayaks that appear similar to the West Greenland style, but often fit more snugly to the paddler and possess a steeper angle between gunwale and stem, which lends maneuvrability.

" The most notable aberration, however, is Stearns Hall, which has been described as " Barbie meets Escher " for its angular, post-modern style and its shrunken scale ( it is supposedly built at 90 % of scale, an idea supported by the feeling of claustrophobia often encountered there ).

Also, the style of the calligraphy used in the inscriptions was an angular version of lishu ( clerical script ) which was generally used in inscriptions on bronze wares and stones during the Han Dynasty.

Sleeping Beauty also signaled a change in the style of drawing with cartoony and angular characters ; taking influence from United Productions of America.

Sleeping Beauty had a more graphic, angular style than previous Disney films, and this look was chosen for One Hundred and One Dalmatians and in most subsequent films.

This album features his composition " Chick's Tune ", a clever retooling of " You Stepped Out of a Dream " that demonstrates the angular melodies and Latin-and-swing rhythms that characterize, in part, Corea's personal style.

Santiago has described his guitar technique as " angular and bent ", and he cites Les Paul, George Harrison, Chet Atkins, Wes Montgomery, Joe Pass and Jimi Hendrix as major influences on his style.

Despite this, the style is appreciated by others, with some of the angular features being softened and updated in buildings currently being constructed in Israel and Latin America, and preservation efforts are taking place in the United Kingdom.

The interiors and exteriors can be described as being of a deconstructivist style, with modern minimalist shapes interspersed with geometry and angular slots.

The Cinquecento was available in one body style only, a small, angular 3-door hatchback, with a favorable drag coefficient of only 0. 33 that bore similarities to the Lancia Y10.

Gone were the angular lines of the superseded model, replaced by what Mitsubishi's new global head of design envisioned as the new Mitsubishi corporate face-a style that would eventually be part of other Mitsubishi vehicles ( e. g. Lancer Evolution and Colt / Mirage ).

The new TR4 body style did away with the classical cutaway door design of the previous TRs to allow for wind-down ( roll-up ) windows ( in place of less convenient side-curtains ), and the angular rear allowed a boot ( trunk ) with considerable capacity for a sports car.

A pirate ship is a type of amusement ride, consisting of an open, seated gondola ( usually in the style of a pirate ship ) which swings back and forth, subjecting the rider to various levels of angular momentum.

One common type used on off-road pickups and SUVs is the " prerunner " style, with an angular, protruding front designed to sweep vegetation away from the vehicle centerline, and to deflect the vehicle from less movable obstacles.

Built in 1468-1472 in late gothic style while, the angular " Erker " was added in 1526.

" Each developed a distinctive but complementary style: Forster's songs were angular and angst-ridden, making much use of irony and unusual lyrical imagery, while McLennan's were generally softer and more sensitive, his lyrics often based on character study and reported speech.

On the outside, with the exception of the doors which were straight from the 2 door Avenger, the R424 was given an all-new body, styled very much in line with Chrysler's new, angular " international " style conceived by Roy Axe, which was first presented with the debut of the 1975 Simca 1307 / Chrysler Alpine, and would later also be represented by the 1977 Simca / Chrysler Horizon ( Project C2 ).

Turn-indicator style lights were used and the gun stick rods were thinner and more angular than those fitted to either TV or film variants.

Until the end of his life Bevan continued to paint in the Bolham valley and nearby Luppitt his angular style sitting well with the strong patterning of the landscape.

The 1500 and 2500 models adopted a more angular style ; the curves of the original design gave way to a raised border forming a lip around the finely-ribbed faceplate, in the middle of which the keypad and number window were centered.
