... A source list compiled by either emldetect or eboxdetect can be added to the RGS source list. ... These EPIC source lists include positions and count rates for each source within several different energy bands. ... The values of the LABEL column of the RGS source list must be unique. For EPIC sources this is partially achieved by including the value of the EPIC source list column ML_ID_SRC or BOX_ID_SRC in the label for that source. ... Note that all LABEL values are converted to upper case. ...

... 2001 May 21 . Another Comet LINEAR Breaks Up . ... Explanation: Last year, a different comet LINEAR (C/1999 S4) broke up. This year, a comet first imaged by the Lincoln Near Asteroid Research (LINEAR) telescope in New Mexico on 2001 January 3, is also breaking up. This new Comet LINEAR (C/2001 A2) unexpectedly brightened to the edge of naked-eye visiblilty a few weeks ago when its nucleus broke in two. ... About APOD | ...

... In order to disentangle the effects of different climate variables on tree-ring growth rates of different species, and to explore the possibility that more than one species could improve the accuracy of the reconstructions of climate using tree rings, a methodical study of trees in close proximity to the Armagh Observatory climate station was initiated together with Ana Maria Garc?a Su?rez, and continued as part of the latter's PhD thesis with John Butler and Professor Mike Baillie (QUB). ...

... Early on, our interest in chirping analysis functions was motivated by a different kind of chirping phenomenon: chirping due to perspective. ... Our interest in radar, however, drew us toward processes that are more accurately analyzed by linear-FM chirplets. ... We have also constructed other chirplet transforms, such as a three-parameter Doppler chirplet representation that models a source producing a sinusoidal wave, while moving along a straight line (e.g. a train whistle). ...

Next: AO data and AIPS++ Up: Spectral-Line Observing at AO Previous: Useful Stuff . There are currently a number of ways you can convert Arecibo data into other data formats, and a variety of support levels for different data analysis programs. As a result it is feasible to reduce your Arecibo data with a wide range of data reduction software. ... In the following two section we describe spectral line data analysis in two of the available data reduction packages - Analyz and AIPS++. ...

... The remote planet Pluto and its moon Charon orbit the Sun at a mean distance of almost 6,000 million kilometres, or nearly fourty times farther out than the Earth. During a recent investigation by an international group of astronomers [1], the best picture ever of Pluto and Charon [2] was secured with the European Space Agency's Faint Object Camera at the Hubble Space Telescope (HST). ... The new HST image was taken when Charon was near its maximum elongation from Pluto (0.9 arcseconds). ...

The efficiency of interaction of radiation with a particle and hence its optical properties depend on the particle chemical composition, size, shape, structure, etc. ...
