It seems that every time I try to correct for a pointing error, I have to figure out the sign of the pointing error as reported by the various routines. The pointing error is computed using the heiles calibration scans and by using the turret scans. ... The center of the pattern is the "computed" position of the source using the ra,dec transformation to az,za and any current pointing model. ... X0, Y0 are reported as the error. ... So for turret scans, Add the az,za error to the pointing model. ...

There are various kinds of generic information you can retrieve about an XPA access point by using the xpaget command. ... Each XPA access point supports a number of reserved sub-commands that provide access to different kinds of information, e.g. the access control for that access point. ... acl get (set) the access control list [options: host type acl, for set] . ...

... Astrometry with the FGS, by contrast, proceeds in the reverse order; the positions of the individual objects are found first, and then a virtual plate is constructed with the help of data from the guide stars and check stars. ... Corrections based on guide star data are referred to as POSITION mode dejittering , and those based on check star data are called drift corrections . ... The adjustments to the astrometry centroids from this POSITION mode dejittering correction are typically about 1 mas. ...

... Bit Fields . Bit Fields: Practical Example . ... NOTE: The combination of pointers and bit-level operators makes C useful for many low level applications and can almost replace assembly code. ... To illustrate many points of bitwise operators let us write a function, Bitcount , that counts bits set to 1 in an 8 bit number ( unsigned char ) passed as an argument to the function. int bitcount(unsigned char x) { int count; for (count=0; x != 0; x>>=1); if ( x & 01) count++; return count; } . ...

... In polar coordinates, the point P is defined by its distance r from the origin O (see drawing) and by its polar angle ("azimuth" on a map) between the x-axis and the "radius" r = OA, measured counter-clockwise. ... When one or both are negative , the angle f is larger than 90 degrees, and such angles never appears in any right-angled triangle. ... There is a simple solution , though: use the above equations to re-define sin f and cos f for such larger angles! ... But it also works for larger angles....

... 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. ...

... Previous: Multi-threaded Query Agent and Engine for a Very Large Astronomical Database . ... Dedicated tools have been developed at CDS in order to face the challenge of fast on-line access to very large astronomical catalogues. ...
