Function Documentation

bool psc::applyStatics	(	const std::map< int, Trace::TimeT > &	shot_st,
		const std::map< int, Trace::TimeT > &	recv_st,
		Trace &	ccfs
	)

Apply statics for provided trace with cross correlations.

Parameters

corr_dir	- correlation directions used mask, ACF alltime skipped.
stride	- used strides, 0 means all strides.
shot_st	- shot based statics.
recv_st	- receiver based statics.
ccfs	- trace with cross correlations to be processed.

Returns

false on error.

double psc::getPartOfZeros	(	const Trace &	tr,
		Trace::AmplT	eps = 0.
	)

Get part of zeros with error of eps for provided trace. For empty trace return 0.

Returns

[0..1] - part of zeros

Trace::TimeT psc::getTimeShiftOfMaxValue	(	const Trace &	ccf,
		Trace::AmplT *	pmax_val = NULL
	)

Gets time shift of maximal value of the trace and sets maximal value if provided.

Trace::TimeT psc::getTimeShiftOfMinValue	(	const Trace &	ccf,
		Trace::AmplT *	pmin_val = NULL
	)

Gets time shift of minimal value of the trace and sets minimal value if provided.

bool psc::isZeroTrace

(

const Trace &

tr

)

Does provided trace completely zero.

bool psc::removeLowFreq	(	const double	sb_size,
		rbm_smooth::Curve &	st_curve
	)

Remove low frequency from statics curve using sliding base smoothing.

Parameters

sb_size	- size of sliding base in term of st_curve[].first coordinate.
st_curve	- curve with statics shifts. st_curve[].first - length along curve, st_curve[].second - time shifts.

Returns

false on error.

bool psc::selectCCF	(	const unsigned int	dir,
		const unsigned int	stride,
		const Trace &	ccfs
	)

Select CCF from provided trace with CCFs inside.

Parameters

dir	- direction of correlation (see CorrDirMask).
stride	- stride of CCF required, 0 means ACF.
ccfs	- trace with CCFs.

Returns

false if no such stride or direction presents.
