Because of the demands on observing time required to obtain spectroscopic redshifts ( i . e ., redshifts determined directly from LSST ) aim to significantly refine the technique.

Fifteen percent of the observing time will be devoted to the public, 20 percent to secondary schools and the rest is for Case Western faculty and students, Luck said.

Despite the publicity surrounding the telescope's tracking of space probes, this only took up a fraction of its observing time, with the remainder used for scientific observations.
44.
"But seven years ago Caltech brought in some partners on the 200-inch, and Cornell astronomers now are allotted 25 percent of the telescope's observing time.
45.
And even if it got off the ground, critics point out that the probe would fly past Pluto so quickly that its observing time would be too short to be worthwhile.
46.
SMARTS contracts with NOAO to maintain the telescopes it controls at CTIO, and NOAO retains the right to 25 % of the observing time, and Chilean scientists retain 10 %.
47.
Starting soon after IUE's launch, a group of European astronomers pooled their observing time to repeatedly observe the galaxy, to measure variations over time of its UV emission.
48.
If two space ships are moving toward each other at velocities that are a substantial fraction of c, an observer in either ship will observe time dilation in the other ship.
49.
:The observational evidence " against " any theory that says time and matter are interchangeable is that no-one has observed time changing into matter or vice versa.
50.
"In my years as a legislator, I've observed time and again that in the international arena, discretion is usually a code word for delay and avoid,"
