!      Ed Westbrook's NOIR-1 CCD detector at ALS 4.2.2 is treated like   
!      the ADSC detectors, except for the rotation axis which points in
!      the opposite direction. 
!
!    WARNING: Since I have not seen the experimental set-up it is well
!             possible that a wrong hand is assigned for the reflection 
!             indices of the data set when using this XDS.INP template!
