... As a consequence, the spectral height and size of the resolution element (resel) have changed. ... The ETC will be updated for phase II of Cycle 21, in the meantime the correction factors given in the Known Issues page of the ETC should be used. ... Since the ETC uses a resolution element that is 5 times smaller (6 pix), it will overestimate the time required to achieve a certain S/N per 30 pixel resolution element, while underestimating the S/N per 30 pixel resolution element for a given time. ...

... We describe enhancements made to Sherpa for the CIAO 2.0 release, concentrating upon those that enable a user to: (1) analyze Chandra X-ray Observatory grating data with wavelength- or energy-space models; (2) simultaneously fit background and source datasets; and (3) estimate and visualize confidence intervals and regions. ... Sherpa is the modeling and fitting tool of the Chandra Interactive Analysis of Observations (CIAO) software package (Doe et al. 1998 and references therein). ...

Underdetermined sets is a new type of data structures (terms) developed in Actor Prolog . ... The point is that an underdetermined set can include some indefinite rest (a tail) like a list in usual Prolog . At the same time, the order of elements of an underdetermined set can be arbitrary one and it does not affect results of unification of underdetermined sets. Moreover, Actor Prolog guarantees that a rest of an underdetermined set never contains elements that are explicitly given in the set. ...

... Bringing news from across the Universe to children all around the world . ... Yet, all of these things are made from the same stuff: chemical elements. ... In total, there are only 118 chemical elements. That means that everything in your room and everything that we can see on Earth is made up from different amounts of some of these chemical elements. ... There might be some extra chemical elements out there, but astronomers only know about 118 chemical elements so far. ...

... The following functions are used to create, manage, and destroy standard doubly linked lists. Each element in the list contains a piece of data, together with pointers which link to the previous and next elements in the list. ...
