Detailed Description

Scan type with z-components of scattering vector as coordinate values.

Wavelength and incident angles are not accessible separately.

Constructor & Destructor Documentation

◆ QSpecScan()

QSpecScan::QSpecScan	(	int	nbins,
		double	qz_min,
		double	qz_max
	)

Sets q-defined specular scan.

Accepts either numpy array of q-values sorted in ascending order or an IAxis object with q-values. Alternatively an axis can be defined in-place, then the first passed parameter is the number of bins, second - minimum on-axis q-value, third - maximum on-axis q_value.

Member Function Documentation

◆ setAbsoluteQResolution()

void QSpecScan::setAbsoluteQResolution	(	const IRangedDistribution &	distr,
		const std::vector< double > &	std_dev
	)

Sets qz resolution values via IRangedDistribution and values of standard deviations.

std_dev can be either single-valued or a numpy array. In the latter case the length of the array should coinside with the length of the qz-axis.

◆ setRelativeQResolution()

void QSpecScan::setRelativeQResolution	(	const IRangedDistribution &	distr,
		const std::vector< double > &	rel_dev
	)

Sets qz resolution values via IRangedDistribution and values of relative deviations (that is, rel_dev equals standard deviation divided by the mean value).
