... The absorption is often saturated with column densities of (10 18 10 20 ) cm 2 , and is preferentially blue-shifted by upto 250 km/s. These absorption systems were thought of to consist of 10 12 solarsystem sized clouds by van Ojik et al. ...
... Suitably scaled units for this problem are solarsystem units, where the mass of the Sun (M ) is taken as unit mass, unit distance is the astronomical unit (AU) and unit time is one year. ...
