Scotch argus Scotch argus The Scotch argus ("Erebia aethiops") is a butterfly of the family Nymphalidae. In spite of its English name "argus", it is not a close relation of the brown argus nor the northern brown argus. Subspecies include: "Erebia aethiops" is widespread in the Palaearctic ecozone, including most of Europe, the Alps and Apennines, Balkans, Asia Minor, the Urals, and the Caucasus. English colonies are found at Arnside Knott and Smardale Gill both in Cumbria. This species is found in most of northern Scotland, and in western areas in south Scotland. In Europe and Russia, these butterflies prefer the edge
ARGUS distribution gives a regular ARGUS, listed above. ARGUS distribution In physics, the ARGUS distribution, named after the particle physics experiment ARGUS, is the probability distribution of the reconstructed invariant mass of a decayed particle candidate in continuum background. The probability density function (pdf) of the ARGUS distribution is: for formula_5. Here formula_6 and formula_7 are parameters of the distribution and where formula_9 and formula_10 are the cumulative distribution and probability density functions of the standard normal distribution, respectively. The cumulative distribution function (cdf) of the ARGUS distribution is Parameter "c" is assumed to be known (the kinematic limit of the invariant
