Function icrar::cpu::PhaseMatrixFunction

Function Documentation

std::pair<Eigen::MatrixXd, Eigen::VectorXi> icrar::cpu::PhaseMatrixFunction(const Eigen::VectorXi &a1, const Eigen::VectorXi &a2, const Eigen::VectorXb &fg, uint32_t refAnt, bool allBaselines)

Form Phase Matrix Given the antenna lists from MS and (optionally) RefAnt & Map: If non-negative RefAnt is provided it only forms the matrix for baselines with that antenna. If True Map is provided it returns the index map for the matrix (only useful if RefAnt set).

This function generates and returns the linear matrix for the phase calibration (only)

Return

std::pair<Matrixd, Matrixi> for refAnt = none: first matrix is of size [baselines,stations] and seconds of size[baselines,1] for 0 <= refAnt < stations: first matrix is of size [stations,stations] and seconds of size[stations,1]

Parameters

  • a1: indexes of 1st antenna of each baselines

  • a2: indexes of 2nd antenna of each baselines

  • refAnt: the reference antenna (0, 1), -1

  • fg: a flag map of flagged stations to ignore when true
