... This makes spatial event selection very hard of even impossible in cases where the object is too faint to clearly stand out against the X-ray background. movecalc takes an event table with aspect corrected X / Y coordinate columns (as generated by task attcalc ) and adds two new columns X_MOV / Y_MOV (different names can be specified via parameters xmovcol / ymovcol ) containing the corresponding coordinates in a reference frame that is centered on the moving object at all times. ...

... Up: Future Instruments and Telescopes, Tools . ... New Generation Astronomical Telescopes (NGAT), a class of telescopes designed to be operated remotely and robotically, require efficient methods for communicating images over heterogeneous and low-bandwidth data networks such as the Internet. ... Methods researched thus far involve the classification of astronomical images based on object parameterisation, progressive image transmission, and evaluation of existing image compression schemes. ...

This diagram illustrates two block boxes, one above the other, with rectangular clipping regions of different dimensions. ... Both axes depict increments of 5px. The clipping region of the first P box lies entirely within it, offset 5px from the top and left edges of the P box, and 10px from the right and bottom edges. ... The clipping region of the second P box resembles that of the first in style and position, except that the right edge is 5px to the right of the P box's right edge. ...

... Microlocal Analysis is a theory of Pseudo-Differential Operators and Fourier Integral Operators (PDOs and FIOs). ... Microlocal analysis comes in few flavors. ... We will consider semi-classical PDOs and FIOs: one can always get from there to standard PDOs and FIOs but semi-classical theory has more applications. Less formal description of (semi-classical) microlocal analysis is ``a semi-classical limit of quantum mechanics'' or ``high-frequency limit of electrodynamics'' (etc). ...

... As stable VLT work horses during the past 8 years obviously the two FORSes have in many ways also been instrumental to the definition of the VLT queue observing paradigm which includes both systematic collection of calibration data, online and offline reduction pipelines. The original concept for the photometric calibration and the FORS imaging pipelines involved acquisition of simple twilight images which were used for flatfielding, and observation of Landolt photometric standards. ...
