... This paper describes the main algorithms used by the Einstein Level One processing to create the exposure masks and the background maps for Einstein IPC images, and how these algorithms were recreated in the IRAF environment. Our goal was to recreate the algorithms used by the Level One Processing to create exposure masks and background maps for Einstein Image Proportional Counter (IPC) data (cf. sections 2.5 and 2.7 of Harnden et al. ...

... I studied a variable star with small light variations found on the Kepler satellite. ... I calculated the surface properties and created a hypothesis of a reflecting binary star system to be the cause of this variation in luminosity. ... I can do this by studying the atomic spectra of the star. ... I found the star to be rich in Helium. I then compared the spectrum against model spectra of Helium rich stars to work out the surface gravity, surface temperature and Helium abundance of the star. ...

The "ring of fire" seen by satellite cameras around the polar caps (picture below) is probably created by electrons leaking from the tail's plasma sheet, whose magnetic field lines form a somewhat imperfect trap. ... One possible explanation involves the close association between auroral arcs and electric currents which flow along field lines between the ionosphere and distant space ( Birkeland currents ). ... That produces an extra resistance to the flow of current. ...

. To remove a directory that is a symbolic link that points to another directory use the command: rm directory_name . Notice that the directory does not need to be empty and you do not have to use the rmdir command. You are not really removing a directory, just a named symbolic link that points to the "real" directory.

... 2001 April 25 . Space Laser Creates Artificial Star . ... So rather than try to eradicate existing stars with a laser, these astronomers create an artificial star of their own right where they need it -- with a laser . Subsequent observations of the artificial laser guide star can reveal information so detailed about the blurring effects of the Earth's atmosphere that much of this blurring can be removed by rapidly flexing the mirror. ...
