Summary of changes:

VIGN:

The NuSTAR vignetting files have been adjusted to improve the fidelity
of the response files near absorption edges caused by W (at 69.5 keV)
in the X-ray optics. The response files are now valid up to 78 keV,
where absorption due to Pt (nominally at 78.4 keV) dominates the response
of the optics. It is recommended that users restrict fitting ranges
to below 78 keV, if possible, to prevent known systematic errors in
the ARF from contributing to continuum fits.
