Exempel på hur man kan använda ARCSECONDS i en mening

• Thus, the speed of the diurnal motion of a celestial object equals this cosine times 15° per hour, 15 arcminutes per minute, or 15 arcseconds per second.
• The legacy of sexagesimal still survives to this day, in the form of degrees (360° in a circle or 60° in an angle of an equilateral triangle), arcminutes, and arcseconds in trigonometry and the measurement of time, although both of these systems are actually mixed radix.
• The angular diameter of the Earth as seen from the Sun is approximately 1/11,700 radians (about 18 arcseconds), meaning the solid angle of the Earth as seen from the Sun is approximately 1/175,000,000 of a steradian.
• RHESSI provided spatial resolution of 2 arcseconds at X-ray energies from ~4 keV to ~100 keV, 7 arcseconds to ~400 keV, and 36 arcseconds for gamma-ray lines and continuum emission above 1 MeV.
• This difference is because the solstices continually precess at a rate of 50 arcseconds per year due to the precession of the equinoxes, i.
• The 13th-magnitude companion, Xi Puppis B, is about 5 arcseconds distant and is a Sun-like star that orbits at least 2000 AU away with an orbital period of at least 26,000 years.
• According to Roorda, in a "perfect" eye, a foveal cone subtends 30 arcseconds, and the diameter of the central "Airy" disk varies between 10 cones (1mm pupil used for reading) to about 1.
• A unique feature of the HETE mission was its capability to localize GRBs with ~10 arcseconds accuracy in near real time aboard the spacecraft, and to transmit these positions directly to a network of receivers at existing ground-based observatories enabling rapid, sensitive follow-up studies in the radio, infrared (IR), and visible light bands.
• 50° is the measure in arcminutes, arcseconds and sixtieths of an arcsecond of the angle whose radian measure is the value of sin 22.
• 74677078493925 = 3437 arcminutes 44 arcseconds 48 sixtieths of an arcsecond = 3437′ 44′′ 48′′′.
• Their stereoacuity is often in the range of 3000 to 70 arcseconds, and a small central suppression scotoma of 2 to 5 deg.
• 4 arcseconds) companion, 2MASS J04414565+2301580 Aab (abbreviated as 2M J044145), which in turn has a nearby small separation substellar companion (separation of 0.
• A bright, type-2 Seyfert galaxy has also been pronounced lying 19 arcseconds from the apparent center of the cluster that has been identified as 2MASX J23444387-4243124, which would later be named Phoenix A, the cluster's central galaxy.
• A group of astronomers investigating the Pan-STARRS 1 images, namely Bryce Bolin, Jan Kleyna, Larry Denneau, and Richard Wainscoat, noticed the object had a diffuse, comet-like appearance with two apparent nuclei separated 3 arcseconds apart and a tail extending more than 14 arcseconds out.
• An ultraluminous X-ray source has been observed 22 arcseconds from the nucleus of the galaxy, which corresponds to about 10 kiloparsec at the distance of the galaxy.
