... This task operates on event data in an event list. ... In the first two cases, the celestial coordinates of the reference point are taken respectively as the values of the RA_NOM , DEC_NOM or RA_OBJ , DEC_OBJ values in the input event file header. ... Although the OM attitude information may be more accurate, it will not be present throughout part of the observation, and as such, the default source for the attitude data should be "ahf". ...

Start= Drop the ball after Energy, Mass and EAS have been set; resume after step or pause has been selected . Step = Drop the ball once and it rebounds to its maximum height and then pauses . ...

... Armagh Observatory, College Hill, Armagh BT61 9DG, +44 (0)28 3752 2928 . ... The low-resolution, Cassegrain mounted, FORS spectropolarimeter of the ESO Very Large Telescope is being extensively used for magnetic field surveys. Some of the new discoveries suggest that relatively strong magnetic fields may play an important role in numerous physical phenomena observed in the atmospheres as well as in the circumstellar environments of certain kinds of stars. ...

... 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. ...

... The data inside CHAMELEON is organized in tables (e.g. ScanTable), structures (e.g. GenConfig), arrays of structures (e.g. scans), and plain arrays (e.g. VisSq). ... RawData: unaveraged, typically 2 ms integrations, flat arrays (bin counts, laser positions, quad cell counts) . ... ScanData: scan averaged data ( scans, bgscans ), output from CHAMELEON, as well as data used in AMOEBA, velocities (spectrosopy) , positions (relative astrometry), magnitudes (photometry), arrays of structures . ...
