... evigweight (evigweight-1.6) [xmmsas_20040318_1831-6.0.0] . ... The instrument (telescope+detector) response is not flat, ie the effective area at a given energy depends on the position in the focal plane, defined by the detector coordinates ( DETX , DETY columns). evigweight sets the stage for an alternative method to building an exposure map (via eexpmap ) adapted to the spectral selection or an effective area (via arfgen ) adapted to the spatial selection, in parallel to images and spectra. ...

... The initial descriptions of the FITS format provided a simplified method for describing the physical coordinate values of the image pixels, but deliberately did not specify any of the detailed conventions required to convey the complexities of actual image projections. ... They were CRPIX n for the reference pixel location on pixel axis n , CRVAL n for the coordinate value at that pixel, CDELT n for the increment at that pixel in the coordinate value, and CTYPE n for the type of coordinate. ...

... The procedure of radiometer signal integration can be considered as a sort of reducing dimension of the initial sampling space, where the samples are the result of analog-to-digital conversion. ... The probability distribution of the signal and spikes is completely known. ... The quality of the considered algorithm could be also illustrated by Figure 2 . ... One could see the considered adaptive algorithm is preferable even by low degree of compression, because all spikes have been depressed. ...

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. ...

... As I mentioned at the recent Groningen international SKA meeting, there is a need for a large-area multi-beaming demonstrator for at least two reasons. ... The LOFAR instrument, to operate in the frequency range 10-250 MHz, will contribute vital information to the design and operation of a new class of multi-beaming telescope. ... The different operating frequency range also means that LOFAR cannot illustrate the scientific potential of area re-use (multi-beaming) in the cm-wave band. ...
