Description:
 def validate_overlap(self,force):
 """Validate that spectrum and bandpass overlap. Warnings are stored in ``self.warnings``. Parameters force : {'extrap', 'taper', `None`} If `None`, it is required that the spectrum and bandpass fully overlap. Partial overlap is allowed if this is set to ``'extrap'`` or ``'taper'``. See :func:`validate_overlap`. """
