Detailed Description

Computes the dispersion delay.

This class computes the dispersion delay between two frequencies, as parameterized by the dispersion measure. Although the value:

$DM\,({\rm pc\,cm^{-3}}) = 2.410331(2)\times10^{-4} D\,({\rm s\,MHz^{2}})$

has been derived from "fundamental and primary physical and astronomical constants" (section 3 of Backer, Hama, van Hook and Foster 1993. ApJ 404, 636-642), the rounded value with three digits of precision is in standard use by pulsar astronomers (page 129 of Manchester and Taylor 1977).
