The VLTI Calibrator Selector Tool is a tool intended to assist in the selection of suitable interferometric calibrators for VLTI observations with MIDI and AMBER. It uses a model of the VLTI and its instruments to assess the fringe visibility, given the observed bandpass, the geometry, spectrum, and coordinates of the target and the time at which the observations are to be made. ... The tool offers an HTML/Java based interface and consists of two pages. ... The quality flag depends on LDD_chi2. ...

. This diagram illustrates how the definition of a pixel depends on the users distance from the viewing surface (paper or screen). The image depicts the user looking at two planes, one 28 inches (71 cm) from the user, the second 140 inches (3.5 m) from the user. An expanding cone is projected from the user's eye onto each plane. Where the cone strikes the first plane, the projected pixel is .28 mm high. Where the cone strikes the second plane, the projected pixel is 1.4mm high. Return to image.

... The ewavelet tasks detects sources using wavelet transforms. ... Figure: Solid line: The mexican hat wavelet function. Dashed line: a gaussian function with the same parameter . ... Since the image is convolved with the MH function the MH acts like a sort of sliding cell: the positive part being the source cell and the negative part being background area. From this it is clear that the wavelet scale should be smaller than the image itself in order to get a well defined image convolution. ...

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 . ...

GENERAL DESCRIPTION OF DATABASE . It is a matter of common knoledge, that solar magnetic fields and, in particular, magnetic fields of sunspots, play important role in many solar events. In Pulkovo observatory the long-term data set of daily observations of magnetic fields of solar sunspots was accumulated, which contains great potential for further researches in solar physics. ... Second section includes files containing sum data about magnetic fields for every observational day. ...
