The maximum error is bigger than the error of lace and is of the order of 9.456 arcsec. The results obtained by NMS are consistent with the measures taken by the ML10.
The last important point is that the intrinsic width of the reflection for the crystal and the apparatus broadening for all the experimental reflections are negligible because these effects amount to only a few arcsec. For this reason, we can only measure the broadening that was caused by the twist only by using (hkl) reflections in skew geometry [8-10, 27].
The standard covariances of the gyro measurement noise and the vector observation noise are 0.5 deg/h and 5 arcsec, respectively.
All of the XRD results showed an improvement in IFELOG, particularly for sample-R, which reduced the GaN (1 0 2) from 600 arcsec to 322 arcsec.
* Reliably endures high mechanical loads even at speeds tip to 5,000 RPAM and 60 arcsec or better accuracy.
Granules vary in size from -0.3-4 arcsec with most having a rough diameter of 1-2 arcsec giving a mean of ~1.35 arcsec (~1,000 km) [14,37,38].
The encoder's ShaftLock system with its large diameter between ABEC5 bearings allows the shaft to reliably endure high mechanical loads even at speeds up to 5000 rpm and 60 arcsec or better accuracy.
The SDO Atmospheric Imaging Assembly (AIA) provides a major advance in the ability of physicists to observe the solar corona: full-Sun 4096 x 4096 images with 0.6 arcsec pixels, in temperatures ranging from chromospheric around 10,000 K up to about 10 million K, with images every 12 seconds, without interruption.
The measured squareness errors are XY = -5.72 arcsec, YZ = 1.73 arcsec and ZX = 3.47 arcsec.
Using a right-angled magnetic air prism, we have achieved a separation of [approximately equal to] 10 arcsec between [approximately equal to] 2 arcsec wide up- and down-spin peaks of 0.54 nm neutrons.
