... A Web browser with Java support and an account to establish a secure Internet HTTP connection to the Goddard Space Flight Center (GSFC), is everything needed in order to use the new Control Center System (CCS). Then full access to the telemetry of the Hubble Space Telescope (HST) is given (Figure 2). A public version of CCS is also available. ...

... They are the offset in arcseconds for the x and y inst plane offset, the exposure time in seconds, and the number of exposures at each position. ... A point about offsets should be made here. The dither program uses absolute instrument plane offsets, so you should use object plane offsets to center up on the chip so that the script starts from where you centered up. INST and OBJ offsets are independent so an object offset will not be zeroed out by and inst plane offset, just added to it. ...

Here user should specify the origin of coordinate system (observer's position). In case of rectangular coordinates it can be center of any major planet or the Sun or any minor planet. ... For spherical coordinates the origin of coordinate system can coincide only with the center of the Earth or with any point on the Earth surface. ... a)by code of observatory in the list of observatories maintained by Minor Planet Center (see IX. Observatories ). b)by introducing name of observatory. ...

... A lightweight stick with two balls of equal weight at its end obviously has its CG in the middle. When one ball is twice the weight of the other, the CG divides the distance between them by a ratio 1:2, in a way that makes it closer to the heavier mass ( see figure ). ... Even though the balls are separate, one can speak of their common center of gravity, on the line connecting their centers, 1/3 of the distance from the center of the heavier ball. ...
