This document discusses the conventions for combining region and table filters, especially with regards to the comma operator. Filter specifications consist of a series of boolean expressions, separated by commas. ... Region and table filters can be combined: foo.fits[circle(10,10,3),pi=1:5] or even: foo.fits[pha==1 (10,10,3),pi==2 (20,20,8,5)] In these cases, it is not obvious whether the command should utilize an or or and operator. ...

... A pair of galaxies has grabbed the attention of astronomers when they were literally thrown into the spotlight. The galaxies were lit up by one of the brightest explosions in the Universe: a Gamma-Ray Burst . Astronomers think that the explosions of massive young stars power these bursts of light. ... By studying the light after it has passed through the galaxies, for example, astronomers can work out what types of atoms they contain, such as oxygen and copper. ...

LBA Disk Recorder Header Format DRAFT ATNF eVLBI Memo #3 Chris Phillips November 15, 2005 1 Introduction The LBA disk recorders currently use a very minimal header for recoded data files (a 16 byte string indicating the start time of the first data sample in the file). ... 2 Header Format The header will consist of a 4096 byte block of ASCII characters. ... Note that if a larger that 4096 byte header is used, the headersize keyword must be within the first 4096 bytes. ...

The ion rocket is another means of providing thrust, more gradually but also more efficiently than a conventional rocket. ... As in the nuclear rocket, the energy which propels the xenon jet comes from a different source; here it is electrical energy from solar cells. The reason an ion rocket is much more efficient than ordinary rockets is the way its jet is produced. ... As with solar sails, solar ion engines are mainly practical in the inner solar system, where ample sunlight is available. ...
