... The fitting procedure will only converge to a unique solution if the components are linearly independent. ... The task calculates for each pair of component images and fails with an error if any is greater than 0.99. ... Hence components may be linearly independent in masked pixels yet still fail the test within the task. ... Finally, since the Poisson image values are necessarily all , negative values are not allowed in the model components. ...

... 8, ``Celestial Mechanics'', 2002 Dynamic evolution of resonance orbits of exoplanets in system 47 Uma B. R. Mushailov, A. A. Kaloshin Sternberg Astronomical Institute, Moscow, Russia The orbits of the major and minor planets of the Solar system indicate that their dynamic evolution is essentially influenced by the effects of orbital reso­ nance interactions. ... One may expect that the orbital resonances can exist not only in the Solar system, but also in other star systems. ...

... For SIMS (Secondary Ion Mass Spectrometry) analysis, a solid surface is bombarded by primary ions of some keV energy. ... The subsequent mass analysis of the emitted ions provides detailed information on the elemental and molecular composition of the surface. ... Extremely short ion pulses with a duration below . ... By rastering a fine-focussed ion beam over the surface, like an electron beam in an electron microprobe, mass resolved secondary ion images (chemical maps) can be obtained...

... The IRAF 2 display server, XImtool, has been enhanced to allow arbitrary custom components to be dynamically integrated, permitting the functionality of the main display server program to be extended in arbitrary ways with no change to the core program. Components may include both computational and GUI elements; new components are interfaced as named instances of the Widget Server Client class and are fully integrated into the base server using messaging. ...

So how do we find objects on the other side of the Universe? ... The latest instruments enable us to scan large areas of sky. Using Cerro Tololo's Blanco 4m telescope and the Canada-France-Hawaii 3.5 metre telescope , we are able to scan a piece of sky larger than the size of the moon every 5 minutes to a faintness level which allows us to find Type Ia supernovae halfway across the Universe. Type Ia supernovae are very rare - but each image we take contains 50000 galaxies. ...
