. To display a clear visual contrast between two text files use the command: sdiff file1 file2 . sdiff displays each line of the two files side by side, making it easier for you to see the difference between them. Lines that are different are shown with a | symbol. Lines unique to file1 are identified by a < symbol; lines unique to file2 with a > . A blank line indicates that the lines are identical. Example .

... The most spectacular view however is from space, where large areas of aurora can be observed simultaneously, even the entire polar cap. ... Such pictures often show a continuous ring of aurora around the polar cap (picture above), caused mostly by electrons leaking out along magnetic field lines, from the plasma sheet of the Earth's magnetic tail. ... Field lines from the auroral oval are believed to lead to the plasma sheet. ... A near-Earth circular polar orbit has many uses. ...

... CI Cam is an X-ray transient and a multiple system which consists of a B4 III-V star displaying B[e] phenomenon, a compact object, probably a white dwarf on an eccentric orbit with the period of 19.407 day (ATEL #416), and a third massive companion of the unknown nature which causes the slow shift of the wind lines of B[e] star (ATEL #1036). ... In the light curve, two waves predominate with periods of 0.4152 and 0.2667 day with the full amplitudes of 0.019 and 0.017 mag, correspondingly. ...

... This task is designed to produce colour plots, the displayed colour at any pixel being a function of the relative intensities in the supplied energy/wavelength bands. Although designed originally to display EPIC X-ray images, it can also be used to create false-colour plots from OM images. ... The created colour image may either be stored in one of the file formats accessible via the pgplot library, or as a 3-plane fits file, or as a ppm image. ...
