Our notes briefly list the optical characteristics that are necessary for radiative transfer (RT) calculations. For further reading we give a list of works developing the RT codes for astronomical applications. ... A part of these notes (the section on the radiative transfer approaches) was addded by V.Il'in S.Grachev. The page of Jurgen Steinacker provides access to several radiative transfer codes, some useful tools, and benchmark results. ...

I tested five Linux boxes connected via Fast Ethernet hub, equipped with three SMC EtherPro cards, one 3c905 and four Intel EtherExpress Pro 10/100. The cable lengths are 65 meters (from hub to Torus and Net3), 38m to Mira and 1m to Zeus and Star. ... File to file . ... 810 Kbytes/sec . 4.2 Mbytes/sec . Zeus . ... P133 64 MB RAM, Linux 2.0.27 tulip.c:v0.10+0.72+0.01 . ... Our main router Net3 Fast Ethernet from two different 10Mb Ethernets runs at the full speed (about 900 Kb/sec). ...

Courses recommended for Astronomy and Astrophysics Honours in 2006 . ... 1st semester 2006: 20 February - 2 June . ... Please note that some of the 1st semester honours courses may run slightly into the teaching free period between 5 June and 14 July. ... This can be either all six courses offered by RSAA (see below) or equivalent honours courses from Geology, Physics or Math. ... Final course date 21. ... Venue: Woolley Seminar Room, RSAA . ...

... An array of vertical electrodes is formed over the silicon surface and horizontal charge transfer columns are defined by implanted channel stop regions in the wafer surface. ... The array operates as follows: when an image is focussed onto the CCD, photons which penetrate the electrode structure generate electron-hole pairs in the underlying silicon substrate, and the signal charges are stored in the potential wells beneath the electrode structure (gates). ...

... 22c. Flight (1) . ... 24a.The Rotating Earth . ... Assuming our rocket and spaceship are provided--how should they be aimed, and how long would the flight take? As an approximation assume that the orbits of Earth and Mars are both circles in the same plane, centered on the Sun. ... That is an ellipse with perihelion P (point closest to the Sun) at the orbit of Earth and aphelion A (point most distant from the Sun) at the orbit of Mars (drawing). ... The length PA of that ellipse is, in AU, . ...
