        element; slit_length
Name Type Occurrence Description Attributes
name string [1..1] Identifies the name of this detector.  
SDD float [0..1] Distance between sample and detector. unit={unit} [1]

:ref:`det.off`

?
container [0..1] Offset of this detector position in X, Y, (and Z if necessary).  

:ref:`det.orient`

?
container [0..1] Orientation (rotation) of this detector in roll, pitch, and yaw.  

:ref:`det.bc`

?
container [0..1] Center of the beam on the detector in X, Y, (and Z if necessary).  

:ref:`det.pixsz`

?
container [0..1] Size of detector pixels in X, Y, (and Z if necessary).  
slit_length float [0..1]

Slit length of the instrument for this detector, expressed in the same units as Q . (See :ref:`rules`)

offset

Name Type Occurrence Description Attributes
x float [0..1] Offset of the detector position in X. unit={unit} [1]
y float [0..1] Offset of the detector position in Y. unit={unit} [1]
z float [0..1] Offset of the detector position in Z. unit={unit} [1] [2]

orientation

Note

The orientation element is intended to describe simple rotations about a single axis rather than a full set of rotations as in a crystallographic context.

pitch float [0..1] Rotation about the X axis (pitch). unit={unit} [1]
yaw float [0..1] Rotation about the Y axis (yaw). unit={unit} [1]

Table Notes

[1](1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)

The unit attribute is required. See :ref:`rules` for acceptable values.

?
[2](1, 2, 3) While z is allowed by the standard (provided by use of a standard size element in the XML Schema), it does not make sense to use it for small-angle scattering in some situations as noted. Use of z in such situations may be ignored by processing software.
