arcsec

The results sent had an average error of 0.194 arcsec and standard deviation of [sigma] = 0.037 arcsec.

Both curves have the same trend and the maximum error is about 5 arcsec. It is important to note that the ML10 did not allow the measurement of the roll error.

Results of initial testing of the instruments show that (though more thorough testing is needed) the standard deviation of less than 1 arcsec can be achieved.

They are thought to represent a greater uplifting of matter and can span from 6-9 arcsec [43] and have lifetimes ranging from 30 minutes to 6 hours [48].

Here we can measure acuity in the same units (arcsec) but the problem is that acuity is affected by contrast and we don't know precisely how to equate the contrast of chromatic and achromatic stimuli.

The speed of the chopping and the 2 arcsec pointing requirement drive the development of the mirror-pointing control system.

The prisms feature a [+ or -] 15 arcsec angular tolerance, which ensures consistent alignment for volume integration.

Magnetic elements have a typical area of 0.1 square arcsec, and lifetime of 5-10 min as tracked from the time series.

The full width at half maximum (FWHM) of the synthesized map is about 18 arcsec and the resulting velocity sampling is [delta]V [approximately equal to] 0.34 km [s.sup.-1].

When the GaN epilayer was grown on the CSS, the FWHM values at the (002) and (102) planes were determined to be 412 and 593 arcsec, respectively.

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.
