cluster_design_matrix

ska_sdp_func_python.calibration.ionosphere_solvers.cluster_design_matrix(mdl_data, mask0, ant1, ant2, coeff, stn2cid, wl_const, n_param, cid)[source]

Generate elements of the design matrix for the current cluster.

Dereference outside of loops and the function call to avoid overheads.

Parameters:

  • mdl_data – [n_time,n_baseline,n_pol] predicted model vis for chan

  • mask0 – [n_baseline] mask of wanted data samples

  • ant1 – [n_baseline] station index of first antenna in each baseline

  • ant2 – [n_baseline] station index of second antenna in each baseline

  • coeff – [n_station] list of basis-func value vectors, one per station

  • stn2cid – [n_station] mapping from station index to cluster index

  • wl_const – 2*pi*lambda for the current frequency channel

  • cid – index of current cluster

  • n_param – number of parameters in Normal equation
