Detailed Description

Class MHO_SpectralLineFringeFitter.

Fringe fitter for narrow-band (spectral-line) VLBI data.

Author

Date

Rather than the broadband (SBD, MBD, delay-rate) search used by MHO_BasicFringeFitter, this fitter works in (channel, intra-channel frequency bin, delay rate) space.

The pipeline is: Configure -> load data, build operators Initialize -> apply flagging / calibration operators PreRun -> run prefit operators, init search operators Run -> coarse (channel x DR x freq) search, fine interpolation PostRun -> run postfit operators Finalize -> store search windows, build plot data

Assumes the polarisation-product axis has size 1 (single pol product or pre-summed coherent combination).

New parameter-store keys set by this fitter (in addition to the standard keys shared with MHO_BasicFringeFitter): /fringe/is_spectral_line (bool) = true /fringe/peak_channel_idx (int) channel index of fringe peak /fringe/peak_freq_bin (int) intra-channel freq bin of fringe peak /fringe/peak_spectral_freq (double) sky frequency of peak (MHz) /fringe/fringe_phase (double) fringe phase at peak (radians)

Standard keys that are set with spectral-line-appropriate values: /fringe/sbdelay = 0 (undefined for narrow-band) /fringe/mbdelay = phase delay (us) (NOT group delay) /fringe/drate = delay rate (sec/sec) /fringe/frate = fringe rate (Hz) /fringe/famp = normalised fringe amplitude
