... The Interactive Spectral Interpretation System (ISIS) is designed to facilitate the interpretation and analysis of high resolution X-ray spectra like those obtained using the grating spectrographs on Chandra and XMM and the microcalorimeter on Astro-E. It is being developed as an interactive tool for studying the physics of X-ray spectrum formation, supporting measurement and identification of spectral features, and interaction with a database of atomic structure parameters and plasma emission...

... JavaScript version 1.3 provides the following new features and enhancements: . ... See the Client-Side JavaScript Guide for details. ... Changes to the Array object. ... The push method returns the new length of the array rather than the last element added to the array. ... Changes to the Date object. ... Added a day parameter to the setMonth method. ... Added the apply method, which allows you to apply a method of another object in the context of a different object (the calling object). ...

... Bojan Nikolic web pages (r. 329) . ALMA . We present a framework for modelling atmospheric phase errors and their correction by both the fast-switching and water vapour radiometeric techniques. ... We use this framework to simulate relative point source sensitivity and effective resolution for a range of atmospheric conditions, with and without phase correction. ... Published as ALMA Memo #582. ... Simulating Atmospheric Phase Errors, Phase Correction and the Impact on ALMA Science . ...

... Unlike clients such as Shout and IceDJ this permits the broadcast of live audio, rather than prerecorded mp3's. LiveIce was developed after the appearance of IceCast to provide the Real Time streaming functionality which makes it a viable solution for broadcasting. It is based on the guts of 2 of my previous works - Mp3Serv, the first mp3 broadcasting system & Mp3Mixer, a toy which allows the user to 'Mix' with mp3 streams. ... LiveIce XMMS sourcecode is available here . ...

Next: CCD Operation Up: Charge Coupled Devices (CCDs) Previous: Charge Coupled Devices (CCDs) . ... However it is only now that a number of important X-ray astronomical applications of CCDs have reached critical development stages, so that this is an appropriate time to review the application of space-borne CCD instruments to cosmic X-ray astronomy, and highlight the particular concerns which are being addressed for X-ray instruments, as distinct from optical applications. ...

Figure 55 shows the ``Green functions'' for the double compact binary merging rate   evolution assuming no collapse anisotropy. ... Another way that diverse peculiarities in the - distribution induced by the sources evolution could arise is connected with a possible non-monotonic character of the star formation rate in galaxies. ... 22 ] Figure  56 shows two-dimensional cuts through the parameter space. ...

Next: Radial velocity of the Up: Optical spectrum of IRAS04296 Previous: Observations and spectra reduction . ... However, molecular emission features are only very rarely observed in the optical spectra of PPNe. ... On the other hand, it is well known that cometary nuclei spectra show prominent Swan band emission. In both spectra of IRAS04296 we have discovered strong emission in the (0;0) and (0;1) bands of the Swan system of the molecule. ... Now consider the case of IRAS04296. ...
