Talk:Moffat distribution

Densities
The may be some confusion over conventions in stating formulae for this distribution. Given that f is decribed as a probability density function, it must integrate to one. Formulae given in "astronomy" literature may be more like weighting functions, and in the case of the density/weight for R there may be an extra multiplication by r or 2r whenever the weight function is used in astromony. There may be a need to state separately how the distribution is actually used in astronomy, but as long as f is decribed as a probability density function, it must integrate to one.

 * Ah, okay! Perhaps a separate expression is required for the usage in Astronomy? —Preceding unsigned comment added by 144.173.229.180 (talk) 09:47, 17 June 2009 (UTC)
