... This window allows the user to manually select new sources from the image to be added to the current list of sources. A source is selected by using the mouse to place the cursor at a particular point on the image and then clicking the left mouse-button to store it. By default, the coordinates of the source will be refined by a moments centroiding algorithm, but this can be switched off by unchecking the centroid button. ...

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. ...

Next: Introduction . ... A spike immunity method of digital integrating radiometer signals in the jamming environment is described. ... The purpose of the method is real-time signal processing, and the basic is an alternative selection of the least offset signal estimation using nonparametric "Nearest Neighbor" rule. ... The additive spike-like jam makes the "tails" of the distribution "heavier" which leads to different offsets for linear and rank mean estimation on the integrating interval. ...

... Up: Description of program searchdup Previous: Program use . Input records are ordered per date of observation, and the list of known (observed) sources is cleared. Each record is compared in position to all the known sources. If the sky distance is less or equal to the specified one, the record is added to the list of observations for that source. If no known sources are within the specified radius, a new source is created, with the coordinates of the observation record. ...
