... The atoms of oxygen, for instance, contain electrons with negative electric charges and protons which are positive, but the two charges balance each other andthe electric and magnetic forces cancel. Magnetic forces have almost no effect on neutral atoms. ... It can be shown that such free electrons and ions will be guided by the magnetic field lines (or "lines of force") which rise from near the southern (magnetic) pole and enter the Earth again near the northern pole. ...

... However to my eye the colour scheme that looks best is what might be described as a `thermal' one, ie one in which cool objects (objects with a long-wavelength excess) are coloured red and hot objects blue, with the intermediate sequence going from red through yellow and white to blue. ... The parameter heat shifts colours along the thermal sequence: at heat = -1 all colours go to red, at +1 they are all blue, with again 0 having no effect. ...
