slipNoise()

bool slipNoise	(	const GObs &	obs,
		const E_FType	freqs[],
		int	nf,
		SlipNoise &	noise )

Derive conservative slip-detector noise from the selected observation bands.

Slip detection chooses concrete observed frequencies with obsFreqs(). The corresponding noise values must come from those same bands; using an arbitrary first signal can pass zero or invalid variances into PDE/SCDIA and produce NaNs in trace output.

This helper requires each selected band to have finite, positive code and phase variance. It then uses the largest selected variance for each observable type as a conservative single-noise input to the current PDE/SCDIA equations.

Parameters

[in]	obs	Observation containing selected signals.
[in]	freqs	Selected frequency bands.
[in]	nf	Number of selected frequencies to validate.
[out]	noise	Derived standard deviations, or failure reason.

Returns

true when all selected bands have usable variances.

traceScdiaEvent()

void traceScdiaEvent	(	Trace &	trace,
		const GObs &	obs,
		const char *	action,
		E_FType	frq1,
		E_FType	frq2,
		E_FType	frq3,
		int	nf,
		E_FilterMode	filterMode,
		double	value1,
		double	value2,
		double	threshold,
		double	amb1,
		double	amb2,
		double	amb3,
		E_SlipDiagReason	reason )

Emit a structured diagnostic line for SCDIA internals.

PDE-SCDIA-DIAG is intentionally separate from PDE-CS-DIAG so existing detector-routing summaries remain stable while SCDIA outcomes become machine-readable.

traceSlipEvent()

void traceSlipEvent	(	Trace &	trace,
		const char *	detector,
		const GObs &	obs,
		const char *	action,
		E_FType	frq1,
		E_FType	frq2,
		E_FType	frq3,
		double	value1,
		double	value2,
		double	threshold,
		E_SlipDiagReason	reason )

Emit one structured cycle-slip diagnostic trace line.

These lines are intended to make detector decisions auditable without changing the detector result. They are emitted at trace level 2 with stable key=value fields so trace files can be summarised with simple text tools.
