| Name | Type | occurrence | Description | Attributes |
|---|---|---|---|---|
| Idata | container | [1..unbounded] | Idata describes a single SAS data point. |
Idata
| 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. | |
| {any} | container | [0..unbounded] | Any element(s) not defined in the cansas1d/1.0 standard can be placed at this point. See {any} for more details. | xmlns:{foreign-prefix}="{foreign-namespace}" |
