Member Function Documentation

Apply()

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

overridevirtual

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.

Implements dp3::ddecal::Constraint.

GetResult()

std::vector<ConstraintResult> dp3::ddecal::TecOffsetDelayConstraint::GetResult ( ) const

inlineoverridevirtual

Obtain results that are to be written to the solution file, instead of the actual solutions. Not all constraints use these; some constraints modify the solutions and the solutions are the result. Example of constraint the do produce results are the Faraday and TEC constraints.

Returns

Optionally, a vector with the last results. The vector is index by value type (e.g. Faraday rotation and scalar).

Reimplemented from dp3::ddecal::Constraint.

Initialize()

void dp3::ddecal::TecOffsetDelayConstraint::Initialize ( size_t  n_antennas, const std::vector< uint32_t > &  solutions_per_direction, const std::vector< double > &  frequencies  )

overridevirtual

Perform common constraint initialization. Should be overridden when something more than assigning dimensions is needed (e.g. resizing vectors).

Parameters

frequencies

For each channel block, the mean frequency.

Reimplemented from dp3::ddecal::Constraint.

SetWeights()

void dp3::ddecal::TecOffsetDelayConstraint::SetWeights ( const std::vector< double > &  weights )

override
