N2 - The "busy function" accurately describes the characteristic double-horn
HI profile of many galaxies. Implemented in a C/C++ library and Python
module called BF_dist, it is a continuous, differentiable function that
consists of only two basic functions, the error function, erf(x), and a
polynomial, |x|^n, of degree n >= 2. BF_dist offers great flexibility
in fitting a wide range of HI profiles from the Gaussian profiles of
dwarf galaxies to the broad, asymmetric double-horn profiles of spiral
galaxies, and can be used to parametrize observed HI spectra of galaxies
and the construction of spectral templates for simulations and matched
filtering algorithms accurately and efficiently.
