Member Function Documentation

◆ compress()

CMVPerTFCompressed o2::tpc::CMVPerTF::compress ( uint8_t flags ) const

Compress this object into a CMVPerTFCompressed using the encoding pipeline described by flags Quantisation (trimGaussianPrecision / roundToIntegers / zeroSmallValues) should be applied to this object before calling compress(); it is not part of the flags pipeline

Definition at line 437 of file CMVContainer.cxx.

◆ getCMV()

uint16_t o2::tpc::CMVPerTF::getCMV	(	const int	cru,
		const int	timeBin
	)		const

Return the raw 16-bit CMV value for a given CRU and timebin within this TF.

Definition at line 373 of file CMVContainer.cxx.

◆ getCMVFloat()

float o2::tpc::CMVPerTF::getCMVFloat	(	const int	cru,
		const int	timeBin
	)		const

Return the float CMV value for a given CRU and timebin within this TF.

Definition at line 384 of file CMVContainer.cxx.

◆ roundToIntegers()

void o2::tpc::CMVPerTF::roundToIntegers ( uint16_t threshold )

Round values to the nearest integer ADC for all values whose rounded magnitude is <= threshold.

Definition at line 408 of file CMVContainer.cxx.

◆ toTTree()

std::unique_ptr< TTree > o2::tpc::CMVPerTF::toTTree ( ) const

Serialise into a TTree; each Fill() call appends one entry (one TF)

Definition at line 691 of file CMVContainer.cxx.

◆ trimGaussianPrecision()

void o2::tpc::CMVPerTF::trimGaussianPrecision	(	float	mean,
		float	sigma
	)

Quantise |v| with a Gaussian-CDF recovery profile: Coarse decimal-style precision below and around mean, then a smooth return to the full native I8F7 precision as the magnitude increases with width sigma

Definition at line 426 of file CMVContainer.cxx.

◆ writeToFile()

void o2::tpc::CMVPerTF::writeToFile	(	const std::string &	filename,
		const std::unique_ptr< TTree > &	tree
	)

static

Write the TTree to a ROOT file.

Definition at line 719 of file CMVContainer.cxx.

◆ zeroSmallValues()

void o2::tpc::CMVPerTF::zeroSmallValues ( float threshold = 1.0f )

Zero out raw CMV values whose float magnitude is below threshold.

Definition at line 395 of file CMVContainer.cxx.
