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. ...

... Suppose that a NS having a rotational magnetic   luminosity forms a binary system (with semi-major axis a ) with a normal star losing matter in the form of stellar wind (with a loss rate ). ... This means that while deriving the formula for a cavern in the general case, we must take into account the proximity of the normal star. ... It follows from the symmetry considerations that at the anterior point of the cavern (i.e. the point closest to the normal star), . ... If , the cavern is closed. ...

... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

GiST home | Introduction | ... GiST is a height-balanced tree structure with tree nodes containing (p, ptr) pairs, where p is a predicate ( attribute ),which is used as a search key, and ptr is the pointer to data for a leaf node or a pointer to another tree node for a non-leaf node. ... Every node contains between min and max index entries unless it is the root . ... For each index entry (p, ptr) in a non-leaf node, p is true when instantiated with the values of any tuple reachable from ptr . ...

... The VSOP Survey Continuum Source List . The radio sample for the VSOP continuum survey was defined to include all extragalactic radio sources with: . a total flux density at 5 GHz, S>=1.0 Jy . ... The sample also included all sources in the sky with a 5 GHz flux density S>5 Jy, regardless of spectral index and galactic latitude. ... The source would then be included in the VSOP sample (three of the sources were found with a flux density above 1 Jy and added to the sample). ...
