While it makes sense for a 3-station array to only record data when all three stations are tracking the fringe (and this is why this mode was used with NPOI's 3-station configuration), NPOI 6-station data from the hybrid beam combiner are recorded even if up to three stations are in fringe search mode. ... Use Util|Edit (located in plot selection widget) to place three rectangular boxes around the bad data points and flag them. ... This step further eliminates bad tracking data. ... Data loaded. ...

... They are concerned with Attitude Control System of the spacecraft, satellite visibility from tracking stations, limits on the satellite autonomous operations during the orbit, and needs for auxiliary operations with the spacecraft. ... Among the operational constraints the most important one is the number of programmed slews per orbit, which determines the maximum number of radio sources to be observed during one orbit. ...

... With enough velocity, a spacecraft can break loose from the Earth's gravity and enter an orbit around the Sun, like that of a planet. If it then orbits the Sun with the same period as the Earth--one year--it may keep a fixed position relative to Earth. ... If the distance is just right--about 4 times the distance to the Moon or 1/100 the distance to the Sun--the spacecraft, too, will need just one year to go around the Sun, and will keep its position between the Sun and the Earth. ...

In this case no hysteresis occurs and transitions E -- P and the reverse take place in symmetrical points of the orbit. ... Here EP means a mixed state of the rotator at which it is in the ejector state during one part of the orbit, and in the propeller state during the rest of the orbital cycle. ...

... XRB SEDs | ... By using RXTE to determine the spectral state of a system we intend to generate SEDs using data that may have been taken at different times but were taken at similar X-ray states. Due to its all-sky coverage and long operational time, the RXTE/ASM instrument provides unparalled information on the spectral states: an ideal jumping-off point for studying time-dependent properties of X-ray binaries. ... Blue arrows designate X-ray observation times. ...

... Unlike clients such as Shout and IceDJ this permits the broadcast of live audio, rather than prerecorded mp3's. LiveIce was developed after the appearance of IceCast to provide the Real Time streaming functionality which makes it a viable solution for broadcasting. It is based on the guts of 2 of my previous works - Mp3Serv, the first mp3 broadcasting system & Mp3Mixer, a toy which allows the user to 'Mix' with mp3 streams. ... LiveIce XMMS sourcecode is available here . ...
