The BP were computed by the aperture method, proceeding from the fild distribution in the aperture of the primary mirror. The components of the main and cross-polarization components of the electric field in the vertical aperture of the primary mirror was computed in Frenel diffraction approximation. ...

... Matching the Surface of Best Focus . ... The plug-plates of SDSS project are responsible for locating the optical-fiber plugs spatially and for defining the plug tilt with respect to the surface of best focus. ... Approximately 670 holes are drilled in each plate. ... In the first attempts to match the curvature of the plug-plates to that of the best focal surface, the bending fixture was set upon 3 6.630mm metal supports that were affixed to a table top and spaced 120 apart. ...

... Moving the sample locations to achieve the desired warping will result in an irregularly sampled image plane. These irregularly spaced samples will then be brought back to regularly spaced positions, hence warping the image. ... The sampled impulse response, , is a function of the sample positions, . ... Allowing the sum to go outside the image boundaries ( or ) includes some ``anchor'' samples outside the image, which tends to stabilize the solution trajectory when is minimized. ...

... The first of the equations defines the position of the spectral orders, m , in the raw image, while the second equation gives, for each order, the dispersion relation in one dimension. ... where the coefficients are computed using least squares techniques on a grid , i.e. sample number and line number of points located within the spectral orders of the image. These points in the grid are found automatically by an order--following algorithm, normally using the FLAT or STD image. ...

SAS home . ... List of SAS threads . OM data processing from A to Z is performed by two "chains": omichain and omfchain , for image and fast mode data respectively. ... Then a source detection algorithm is used to identify the sources present in the image. ... A final source list is obtained from all exposures and filters. ... If the user has PPS products from the processing of his/her observation, or from the XSA, then the first thing to do is to overlay the image source list onto the sky image. ...

... July 29, 1998 . The High Energy Heart Of The Milky Way . ... Explanation: These high resolution false color pictures of the Galactic center region in high energy X-ray and gamma-ray light result from a very long exposure of roughly 3,000 hours performed from 1990 to 1997 by the French SIGMA telescope onboard the Russian GRANAT spacecraft . ... But according to recent theories , only those binary systems with black holes can radiate above X-ray energies -- in the gamma-ray regime. ...

SOME RESULTS FROM INTMINS . The experiment can be performed when the electron beam (instrument ISTOCHNIK ) and plasma blobs (instrument ARIEL ) are injected approximately along or perpendicular to the Earth's magnetic field. ... The pulses of frequency of 1000 Hz will generate EM waves and its harmonics. ... To increase the electron gun pulse duration up to D t = 0.5 f -1 ( D t = 5x10 -4 s) and to stabilise their frequency as good as possible. ... Back to the INTMINS Main Page ...

Next: Getting Information After UVREAD Up: UV Data Sets Previous: Setting Up UVWRITE - . ... Another function performed by uvread is skip or flag data that is not required. ... Generally uvselect will be called many times, each call giving a different selection or discard criteria. ... Hence the `grammar' of the sequence of calls to uvselect (i.e. use of ``or'', or multiple occurrences of criteria based on the same parameter) is the same as the `grammar' of the user-specified task parameter. ...

Results from a series of long-term numerical integrations of orbits centred on that of C/1995 O1 (Hale-Bopp) are presented. Initially, 33 orbits taken from various sources were integrated in realistic models of the solar system for various time-scales about the present in the range (-3, +2) Myr and analyzed to assess the probability of different dynamical outcomes, such as a sungrazing state or the number of orbits since it was captured from a long-period orbit in the Oort cloud. ...
