... Return the telescope effective area in square cm averaged over the given energy band and at a specified position in the telescope field of view. ... the effective area at any position in the field of view is calculated from an on-axis effective table and from a set of vignetting tables provided in the CCFs. The vignetting tables are normalized to one on-axis and are provided as a function of the off-axis angle for energies ranging from 100 eV to 15 keV. ...

... We present a computer program for modelling energy flux distribution and light curves of eclipsing binaries from far ultraviolet to infrared regions. The Roche model is assumed. Proximity effects of components (reflection of radiation and surface gravity darkening) are taken into account. ...

The target XD location is assumed to be the median position (NUV) or mean position (FUV) of the collapsed spectrum. ... If the target is centered in the aperture, but the Y walk shifts its spectrum in the XD direction, then the ACQ/PEAKXD algorithm will miscalculate its centroid and move the target away from the aperture center. ...

... This is possible at modest cost due to the low moments of inertia of the telescope and enclosure. ... This same performance will be achieved in higher winds when the telescope enclosure is facing away from the wind, or by using wind screens. ... The telescope system (MILT) will be remotely operable with an on-site operator's assistance by an astronomer located at one of the ARC member institutions. ... Mean Wind Speed . ...

Next: The Echelle Relation Up: Wavelength Calibration Previous: Wavelength Calibration . A preliminary step to the wavelength calibration consists of extracting the orders of the WLC image which can then be used to determine the dispersion relation in two steps: . ... Both methods are based on the echelle relation and therefore are not applicable if the disperser is not an echelle grating, as it is the case for EFOSC which involves a grism disperser. ...

. This diagram shows a small table with three transparent cells and illustrates how their final background is determined. The table consists of two rows. Four (labeled) cells lie in the first row, but the second cell spans the first and second row. The first, third, and fourth cells of the second row are "empty". Each non-empty cell has a red background and a double black border. Each empty cell has the table's background color (specified as #ff0) as its own. Return to image.

... 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. ...
