... Judged by their instrumental profiles, spectrometers fall into two basic classes---Lorentzian and Gaussian---with many other line profile functions (sinc functions, Voigt functions, Airy functions, etc.) falling into one of these two categories in some limit. We demonstrate that the Rayleigh, Sparrow, and Houston resolution criteria are of limited use compared to the ``equivalent width'' of the line profile. ... Rayleigh criterion. ... All of these functions have continuous higher derivatives. ...

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. ...

... 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 . ...
