Computation and Utilities

The computation utilities provide essential helper functions and calculations for fringe fitting operations, including SNR calculations, error analysis, and plot data computation.

MHO_BasicFringeInfo

Class	MHO_BasicFringeInfo
Primary Functionality	Static helper functions for fringe information calculations
Key Features	SNR calculations with various correction factors Error calculations for delays and rates Phase calculations and corrections Theoretical RMS calculations

The MHO_BasicFringeInfo class provides a collection of static helper functions for computing fringe information and parameters. This includes the signal-to-noise ration (SNR) and probability-of-false-detection (PFD) calculation, error coding/flagging functions, and phase correction calculations. Some functions include calculate_snr() for signal-to-noise ratio calculations, calculate_mbd_no_ion_error() for multi-band delay error estimation, and calculate_pfd() for probability of false detection calculations.

MHO_BasicFringeUtilities

Class	MHO_BasicFringeUtilities
Primary Functionality	Helper functions for fringe fitting organization
Key Features	Sideband average calculations Residual phase calculations Sampling rate determination SNR correction factors

The MHO_BasicFringeUtilities class provides organizational helper functions for fringe fitting operations. It includes sideband averaging, residual phase calculations, and SNR correction factor computations.

Some key functions include calculate_sbavg() for sideband average calculations, calculate_fringe_solution_info() for fringe solution parameters, and calculate_snr_correction_factor() for bandwidth corrections (if notches or passband have been used).

MHO_ComputePlotData

Class	MHO_ComputePlotData
Primary Functionality	Fringe plot information computation
Key Features	Multi-band delay (MBD) and single-band delay (SBD) calculations Cross-power spectrum computation Frequency and time domain RMS calculations Fringe quality and error code generation

The MHO_ComputePlotData class computes fringe plot information required for visualization and analysis. It provides the main set of calculations needed for power spectra, RMS values, and quality assessment metrics that form the basis of the fringe plot.

Some key functions include calc_mbd(), calc_sbd(), and calc_dr() for fringe amplitude vs. fit paramater plots. It also provides calc_freqrms() and calc_timerms() for RMS calculations, and calc_quality_code() and calc_error_code() for fringe quality assessment.
