The observation accuracies were found to be 11 to 17 arcseconds
in right ascension and 1.
In combination with the 640 x 480 Aptina MT9V011 image sensor , this gives a resolution of 262 arcseconds
per pixel and a field of view of 46 x 35 degrees.
by the end of the period, at which time it will be rising some 45 minutes before midnight.
is achieved - sufficient to see a golf ball being held 150 km (100 miles) away.
One way to distinguish an asteroid from a star is by its motion, typically 30 arcseconds
per hour relative to the background stars.
75[degrees] with a resolution of 5 arcseconds
The typical spatial resolution of those observations is 15 arcseconds
or larger (1 arcsecond
corresponds to 1/3600 of 1 degree), however, ALMA achieved a high resolution of 3.
(1/36,000 of a degree) in angle compared to the official reference value.
One arcminute is divided into 60 arcseconds
(60"), which is about the resolution of the human eye.
, improving slowly but surely for imagers and observers.
across-the equivalent of a dime viewed from more than a hundred miles away.
The nebula is about 250 arcseconds
in diameter and surrounds the magnitude 8.
If the bullet model is correct and the shaft isn't simply an artifact of the image, then future Hubble photographs taken a year apart should show the material moving 2 to 3 arcseconds
, about 0.
Measured in degrees ([degrees]), arcminutes O and arcseconds
The feature is approximately 25,000km across which equates to an angular diameter of just under 4 arcseconds
when the planet was at opposition on April 28.
