The interesting discovery was that despite the stated accuracy of instruments (5 arcsec
They are thought to represent a greater uplifting of matter and can span from 6-9 arcsec
 and have lifetimes ranging from 30 minutes to 6 hours .
3), obtained by rotating the analyzer crystal, reduced to nearly 2 arcsec
This may appear mysterious but when optical blurring is taken into account, it is found that a 5 arcsec
shift in the position of a line implies a 2 per cent contrast shift in the photoreceptor best placed to detect the shift.
It dynamically positions the mirror to 2 microns, removing gravitational sag and chopping 26 arcmin in 10 milliseconds to an accuracy of 2 arcsec
to remove thermal effects.
s PATCHLINK UPDATE(TM) 6 has received an "excellent" ranking as reported in a product comparison conducted by ArcSec
Technologies, a provider of independent, third-party analyses of security technologies and products.
At the time the comet was approaching the Sun some 4 months before perihelion, and exhibited a disk-like coma about 85 arcsec
in diameter (Figure 1).
In the mid-to-end 17th century, Flamsteed, the first Astronomer Royal, produced a northern hemisphere catalogue accurate to about 10 arcsec
This parallelism between the substrate and the component is to measure and adjust in a range of A 2 A and a resolution of about 1 arcsec
of pointing stability - that's world class for the equipment that we have on the ground, but hard to achieve in the air where there are wind forces and acoustic forces buffeting the telescope.
Short description of the contract or purchase What is required is a modular high-resolution X-ray diffractometer according to the latest state of the art, which must cover, without any restrictions, the following modes: (A) High-resolution RE[micro]ngtendiffraktometrie with parallel beam optics and primary and secondary divergence of 12 arcsec
, for highest resolution reciprocal space maps and the corresponding individual scans for symmetric, asymmetric and symmetric diagonally-reflexes.
