Detailed Description

This class constrains the phases of the solution to be zero, but keeps the amplitude information.

Member Function Documentation

void dp3::ddecal::AmplitudeOnlyConstraint::Apply	(	SolutionSpan &	solutions,
		double	time
	)

inlineoverridevirtual

This method applies the constraints to the solutions.

Parameters

solutions	A 4D array with dimensions n_channel_blocks x n_antennas x n_sub_solutions x n_pol solutions. n_pol is the dimension with the fastest changing index. Using a span instead of a real tensor as argument type avoids the need for copying data in Python bindings.
time	Central time of interval.
