Detailed Description

Parses and queries TPC sector edge fluctuation intervals from a CSV text file.

Expected line format (comma-separated, whitespace around tokens is ignored): runNumber, startMS, endMS, durationMS, label[, SectorID[=scale], ...]

The sector list is optional. If omitted (or all tokens fail to parse), the interval is applied to all 36 sectors (A0-A17 and C0-C17) with scale 1.0.

Examples: 560352,1732244770094,1732244771094,1000,edge distortions,A3 560352,1732244771344,1732244776344,5000,edge distortions,A3=1.2,C0,C1=0.6,C2,C3

If the same sector appears in multiple overlapping intervals at a queried timestamp, the scale from the interval with the latest end-time is used.

dumpToFile()

void o2::tpc::SectorEdgeFluctuations::dumpToFile	(	const char *	file,
		const char *	name = "ccdb_object",
		const char *	brName = "SectorEdgeFluctuation"
	)

dump this object to a file

Parameters

file	output file
name	name of the output object

Definition at line 214 of file SectorEdgeFluctuations.cxx.

empty()

bool o2::tpc::SectorEdgeFluctuations::empty ( ) const

inline

Definition at line 94 of file SectorEdgeFluctuations.h.

getIntervals()

const auto & o2::tpc::SectorEdgeFluctuations::getIntervals ( ) const

inline

get stored data

Definition at line 97 of file SectorEdgeFluctuations.h.

getNRuns()

size_t o2::tpc::SectorEdgeFluctuations::getNRuns ( ) const

inline

number of total runs stored

Definition at line 93 of file SectorEdgeFluctuations.h.

getSectorsAtTime()

std::vector< std::pair< int, float > > o2::tpc::SectorEdgeFluctuations::getSectorsAtTime	(	int	run,
		Long64_t	timestampMS
	)		const

Returns all {o2SectorId, scalingFactor} pairs active for the given run at the given Unix timestamp (milliseconds). Returns empty if none are active or if the run is not known.

Definition at line 178 of file SectorEdgeFluctuations.cxx.

loadFromCSVFile()

bool o2::tpc::SectorEdgeFluctuations::loadFromCSVFile

(

const std::string &

filename

)

Load intervals from file. Clears any previously loaded data. Throws std::runtime_error if the file cannot be opened.

Definition at line 56 of file SectorEdgeFluctuations.cxx.

loadFromFile()

void o2::tpc::SectorEdgeFluctuations::loadFromFile	(	const char *	inpf,
		const char *	name = "ccdb_object",
		const int	iEntry = 0,
		const char *	brName = "SectorEdgeFluctuation"
	)

load from input file (which were written using the dumpToFile method)

Parameters

inpf	input file
name	name of the object in the file

Definition at line 225 of file SectorEdgeFluctuations.cxx.

parseSectorId()

int o2::tpc::SectorEdgeFluctuations::parseSectorId ( const std::string &  sectorStr )

static

Convert a sector string such as "A3" or "C14" to the O2 integer sector index (0-35). Returns -1 on parse error.

Definition at line 31 of file SectorEdgeFluctuations.cxx.

setFromTree()

void o2::tpc::SectorEdgeFluctuations::setFromTree	(	TTree &	tree,
		const int	iEntry = 0,
		const char *	brName = "SectorEdgeFluctuation"
	)

set this object from input tree

Definition at line 240 of file SectorEdgeFluctuations.cxx.

size()

size_t o2::tpc::SectorEdgeFluctuations::size ( ) const

inline

Total number of intervals across all runs.

Definition at line 83 of file SectorEdgeFluctuations.h.
