... Interferometric data files handled by CHAMELEON use the HDS (Hierarchical Data System) format, and have an extension .con for point data files output by CONSTRICTOR and .cha for scan-averaged data output by CHAMELEON. Think of the HDS format as a UNIX directory/file tree contained within a single file. ... The .con files are found in /data/npoi/con on gemini. Output files produced by CHAMELEON are always stored in the current working directory. ...

. This diagram illustrates how anonymous block boxes may spring into existence around anonymous content. It shows two rectangular boxes that contain text, the first being anonymous. It has a light grey background and contains the words "Some text". Just below it is a P box with a dark grey background that contains the words "More text". The boxes are both within a DIV box.

... After all we cannot send a probe to the star Altair to confirm that it is 17 light years away. ... The "Bessel determined that the star 61 Cygni was about ten light years away" Earth goes around the Sun in one year, so in six month it is in the opposite position in its orbit. ... In 1838 Bessel determined that the star 61 Cygni had a parallax of 0.314 arcseconds and therefore the star was about ten light years away (today the distance is more precisely measured to be 11.4 light years). ...
