Python Reference Introduction These notes contain commands useful for analysing and plotting data using the Python programming language, together with the Numpy and Matplotlib libraries. ... So for example, the plot command (from matplotlib) would be executed by typing pylab.plot(.. ... Pulling out part of an array. ... To pick out only the chosen elements, and put them in a new array, use something like: new_array = my_array[index_array] Plotting We use Matplotlib (included in pylab) to plot. ...

Grazing incidence imaging from 10 to 40 keV Martin Elvis, Daniel G. Fabricant, and Paul Gorenstein The prospects for imaging x rays at energies from 10 to 40 keV with grazing incidence optics are explored. ... The reflectivity of a sample of iridium-coated float glass was measured at small grazing angles (25-5 min of arc) at energies of 8,17, and 26 keV. ... The grazing angle at 30 keV is -10 min of arc. ... At 10-min of arc grazing angle the reflectivity they measured drops sharply beyond 10 keV. ...

... GCR and SCR are primary cosmic rays. 10-15 years after the discovery of cosmic radiation (1919) there emerged two main avenues of investigation in the physics of cosmic rays (CR): 1) nuclear - elucidation of the origin of elementary particles and nuclear interactions; and 2) astrophysical (space physics) - solution of the problem related to the origin and variations (changes in intensity) of CR. ... Besides, the CR flux in interplanetary space is, strictly speaking, not isotropic. ...
