... 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. ...

The File System . This section describes how you can create new files, copy existing files, and delete obsolete files. ... RENAME to change the name of a file. ... Files can be created in several ways: text can be entered from the keyboard via the CREATE command, an editor can create a file, as can a running program, and files can be copied from other directories. ... To delete obsolete files, use the DELETE command followed by a file name or file name template (wildcards). ...

. To create a file with the cat command: cat > memo remember to make appointment at opticians get cost of scheduled flight to Athens Ctrl-d . This creates a file called memo in the current directory containing two lines of text. To create a file with the echo command: echo use an editor for large files > tips . This creates a file called tips in the current directory containing a single line of text.

... April 9, 1999 . WR 104: Pinwheel Star . ... Explanation: Like a cosmic lawn sprinkler, dust streaming from a rotating star system creates a pinwheel pattern in this false color infrared image . Astronomers discovered the surprising star dust scenario using a sophisticated interferometer and the 10 meter Keck I telescope to observe the bright Wolf-Rayet star WR 104. ... The problem is, their starlight would also be so intense that any dust flakes should be destroyed! ... About APOD > . ...

. In an effort to provide a centralized database for indexing locations and descriptions of Shuttle debris, the editors of Astronomy Net have generated a database and web page where reports can be logged. This may or may not prove useful for cataloging debris reports, but Astronomy Net is happy to dedicate computer resources to help out any way possible. We express our sympathy and prayers to the families and friends of the Columbia crew. If you have located Shuttle debris, report it here.

... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

... This program was created for correlating chosen regions in the series of fts images. ... Chosen regions' . ... In this section the program counts the integral for each region of the grid for each image. ... As a matter of fact, the integral is total brightness of the region and it is counted by 'int_tabulated' IDL function. ... In addition, the program will show the count of the regions which correlate with the corresponding region (the brighter region means the bigger count) and its contour. ...

... Aurora from Space . ... Magnetic Storms . ... 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 ). ... Why no aurora at the magnetic poles? ...
