* %Description
*
* The H16@ILL curved guide sending cold neutrons from the VCS to IN5.
*
* %Example: m=1 Detector: GuideOut_Phic_I=1.85e+10
*
* %Parameters
* m: [1]         m-value of whole guide coating. 0 absorbing, 1 for Ni, 1.2 for Ni58, 2-4 for SM
* lambda: [AA]   mean incident wavelength.
* dlambda: [AA]  wavelength half width. Use e.g. 0.8*lambda for white beam.
