  We describe the application of the `low-$\nu$' method to the extraction of
the neutrino flux at MiniBooNE energies. As an example, we extract the relative
energy dependence of the flux from published MiniBooNE quasielastic scattering
cross sections with $\nu < 0.2$ GeV and $\nu < 0.1$ GeV (here $\nu$ is the
energy transfer to the target). We find that the flux extracted from the
`low-$\nu$' cross sections is consistent with the nominal flux used by
MiniBooNE. We fit the MiniBooNE cross sections over the entire kinematic range
to various parametrizations of the axial form factor. We find that if the
overall normalization of the fit is allowed to float within the normalization
errors, the extracted values of the axial vector mass are independent of the
flux. Within the Fermi gas model, the $Q^2$ distribution of the MiniBooNE data
is described by a standard dipole form factor with $M_A=1.41\pm0.04$ GeV. If
nuclear transverse enhancement in the vector form factors is accounted for, the
data are best fit with a modified dipole form factor with $M_A=1.10\pm 0.03$
GeV.
