1. Thermal History of the Universe
The above process keeps the # of protons and the # of neutrons in the early Universe constant. This is extremely important and will result in a testable prediction later. Remember, a free neutron (one that is not bound in an atomic nucleus) will decay into a proton + electron (+ anti-neutrino) in about 900 seconds. ... During this epoch, the proton-to-neutron ratio is 1.0 . ... The Universe consists of protons, neutrons and electrons plus a photon background and a neutrino background. ...

2. Recreating Einstein Level One Processing Exposure Masks and Background Maps in
... 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. ...

3. EBCCD tutorial background
BACKGROUND . ... Electron bombarded silicon (EBS) gain makes the CCD interesting for keV electron detection. Ionizing particles absorbed in silicon create electron-hole pairs at the average rate of one per 3.64 eV incident energy. ... The variance in the number of electron-hole pairs created is given by the Fano factor for silicon (.1-.2) times the number of pairs created. When we use a CCD as a detector of ionizing particles, we would like to collect all of the electrons created. ...

4. Creation of background spectrum and lightcurve; screening of periods of high
... If requested ( runbackground =Y), the task creates a background lightcurve, as well as a background spectrum for the imaging modes (FF, eFF, LW, SW) using background masks. ... The background masks are created by task badpixfind using threshold parameters, appropriate for the detection of real X-ray sources. ... As the GTIs strongly depend on the intended science this screening is not performed and only background masks, the lightcurve, and a GTI file are created by epchain . ...

... 2009 April 27 . Prometheus Creating Saturn Ring Streamers . Credit: Cassini Imaging Team , ISS , JPL , ESA , NASA . ... Specifically, an orbital dance involving Saturn's moon Prometheus keeps creating unusual light and dark streamers in the F-Ring of Saturn. Now Prometheus orbits Saturn just inside the thin F-ring , but ventures into its inner edge about every 15 hours. ... Since Prometheus orbits faster than the ring particles, the icy moon pulls out a new streamer every pass. ...

8. Examples of creating files
. 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.
