Name | Type | occurrence | Description | Attributes |
---|---|---|---|---|
Q | floating-point number | [1..1] | Q=(4 π / λ) sin(θ) where λ is the wavelength of the radiation and 2θ is the angle through which the detected radiation has been scattered.
The unit attribute is required. See cansas1d_documentation#Rules for acceptable values. Either 1/A or 1/nm are typical. |
unit="{units}" |
I | floating-point number | [1..1] | Intensity of the detected radiation.
The unit attribute is required. See cansas1d_documentation#Rules for acceptable values. One possibility might be1/cm. |
unit="{units}" |
Idev | floating-point number | [0..1] | Estimated standard deviation of I.
The unit attribute is required. See cansas1d_documentation#Rules for acceptable values. One possibility might be1/cm. |
unit="{units}" |
Qdev | floating-point number | [0..1] | Estimated standard deviation of Q. (optional: see note below on usage)
The unit attribute is required. See cansas1d_documentation#Rules for acceptable values. Either 1/A or 1/nm are typical. |
unit="{units}" |
dQw | floating-point number | [0..1] | Q resolution along the axis of scanning (the high-resolution slit width direction). Useful for defining resolution data from slit-smearing instruments such as Bonse-Hart geometry. (optional: see note below on usage)
The unit attribute is required. See cansas1d_documentation#Rules for acceptable values. Either 1/A or 1/nm are typical. |
unit="{units}" |
dQl | floating-point number | [0..1] | Q resolution perpendicular to the axis of scanning (the low-resolution slit length direction). Useful for defining resolution data from slit-smearing instruments such as Bonse-Hart geometry. (optional: see note below on usage)
The unit attribute is required. See cansas1d_documentation#Rules for acceptable values. Either 1/A or 1/nm are typical. |
unit="{units}" |
Qmean | floating-point number | [0..1] | Mean value of Q for this datum. Useful when describing data that has been binned from higher-resolution or from area detectors.
The unit attribute is required. See cansas1d_documentation#Rules for acceptable values. Either 1/A or 1/nm are typical. |
unit="{units}" |
Shadowfactor | floating-point number | [0..1] | Describes the adjustment due to the beam stop penumbra.
(This definition needs revision. NIST?) NOTE: There is no "unit" attribute. |
