 With VULCAN's offsets in TOF, the calibration is done as the following.

 Therefore, by defining :math:`\xi^{(v)}` as the VULCAN's offset, and :math:`\xi^{(m)}` as
 the Mantid's offset, then we can convert VULCAN's offset to Mantid's as
- :math:`\xi^{(m)} = \frac{L\cdot\sin\theta}{L'\cdot\sin\theta'}\cdot\frac{1}{\xi^{(m)}} - 1`

 VULCAN uses effective DIFC and :math:`2\theta` for the effective detector to be focussed on.
 It follows the Bragg rule for time-of-flight, i.e.,
