... NASA Headquarters, Astrophysics Division, Washington DC . The Astrophysics Program at NASA is mission oriented. With seven flying missions and twenty additional (international collaborations) planned, NASA provides an ever increasing amount of exciting astrophysical data, and supports a large portion of astrophysics data analysis. ... The future contains many changes that offer us significant challenges. ... Other restructuring plans affect the data analysis plans for several flying missions. ...

Next: Scattering properties Up: Polarization properties (transmitted radiation) Previous: Linear polarization: wavelength dependence . Traditionally, the main problem considered in connection with circular interstellar polarization is the meaning of the wavelength where changes the sign . ... This is also demonstrated by Fig. 19 (lower panel) which shows the wavelength dependence of the factors of linear and circular polarization for particles of magnetite as was done by Shapiro ([ 1975 ]). ...

. The range of offshore 8m-class telescopes to which Australian astronomers have access is about to undergo significant changes. I will outline the extensive suite of facilities on the Gemini, Magellan, and Keck telescopes to which all Australian astronomers will be able to apply for from now through to the end of 2017. The International Telescopes Support Office at the AAO is positioning itself to support users of these facilities in a range of ways that I shall discuss.

Unless you specify otherwise sort treats the one or more space characters between words as field delimiters. You may want to sort files where words are separated by another character such as a colon ( : ). Use the -t option to specify another character to act as the field delimiter. For example -t: . specifies the colon ( : ) character as the delimiter. One specific delimiter followed by another indicates an empty field. ... field2 is taken to be empty. ...
