void StBbcGeom::GetCorners	(	short	tileId,
		double *	x,
		double *	y
	)

returns the 6 corners of the hexagonal tile in STAR Coordinates

Parameters

tileId	\|tileId\| = 1..18 (inner BBC). Sign of tileId tells side. +/- for West/East
x,y	pointers to arrays of six corners

Definition at line 121 of file StBbcGeom.cxx.

void StBbcGeom::GetCorners	(	unsigned short	absValueTileNumber,
		short	eastwest,
		double *	x,
		double *	y
	)

returns the 6 corners of the hexagonal tile in STAR Coordinates

Parameters

absValueTileNumber	this is a positive number between 1 and 16, inclusive
eastwest	<=0 for East, >0 for West
x,y	pointers to arrays of six corners

Definition at line 136 of file StBbcGeom.cxx.

void StBbcGeom::GetOverlappingEpdTiles	(	short	tileId,
		int *	nOverlappingEpdTiles,
		short *	EpdTileIDs
	)

returns a list of (the IDs of) EPD tiles that overlap with a given BBC tile

Parameters

tileId	\|tileId\| = 1..18 (inner BBC). Sign of tileId tells side. +/- for West/East
nOverlappingEpdTiles	output parameter. Number of EPD tiles that overlaps this BBC tile (0, 8, or 10)
EpdTileIDs	output parameter: list of EPD Tile IDs

Definition at line 161 of file StBbcGeom.cxx.

void StBbcGeom::GetOverlappingEpdTiles	(	unsigned short	absValueTileNumber,
		short	eastwest,
		int *	nOverlappingEpdTiles,
		short *	EpdTileIDs
	)

returns a list of (the IDs of) EPD tiles that overlap with a given BBC tile

Parameters

absValueTileNumber	this is a positive number between 1 and 16, inclusive
eastwest	<=0 for East, >0 for West
nOverlappingEpdTiles	output parameter. Number of EPD tiles that overlaps this BBC tile (0, 8, or 10)
EpdTileIDs	output parameter: list of EPD Tile IDs

void StBbcGeom::GetTilesOfPmt	(	unsigned short	pmtNumber,
		unsigned short *	nTiles,
		unsigned short *	tileNumbers
	)

returns the NUMBER OF TILES and the tile numbers corresponding to a given phototube the BBC is such a pain in the neck this way!! most PMTs correspond to one tile only. But PMT #7 corresponds to tiles 7 and 9, and PMT #12 corresponds to tiles 13 and 15 At least the correspondence is the same on both sides

Parameters

pmtNumber	phototube number, from 1 to 16, inclusive
nTiles	output parameter, either 1 or 2. tells the number of tiles corresponding to the PMT
tileNumbers	array of tile numbers, between 1 and 18, corresponding to the PMT

Definition at line 97 of file StBbcGeom.cxx.

bool StBbcGeom::IsInTile	(	short	tileId,
		double	x,
		double	y
	)

returns true if (x,y) lies within the tile. Assumes z=zWheel useful if the user would like to project a track (using straight line of helix or whatever) to the plane of the wheel and determine whether it hit a given tile

Parameters

tileId	\|tileId\| = 1..18 (inner BBC). Sign of tileId tells side. +/- for West/East
x	x-coordinate of projected hit
y	y-coordinate of projected hit

Definition at line 147 of file StBbcGeom.cxx.

bool StBbcGeom::IsInTile	(	unsigned short	absValueTileNumber,
		short	eastwest,
		double	x,
		double	y
	)

returns true if (x,y) lies within the tile. Assumes z=zWheel useful if the user would like to project a track (using straight line of helix or whatever) to the plane of the wheel and determine whether it hit a given tile

Parameters

absValueTileNumber	this is a positive number between 1 and 16, inclusive
eastwest	<=0 for East, >0 for West
x	x-coordinate of projected hit
y	y-coordinate of projected hit

unsigned short StBbcGeom::PmtOfTile ( unsigned short tileNumber )

inline

returns the phototube number (beginning at one) corresponding to the tile number (beginning at one) it is the same on the East and West sides

Parameters

tileNumber inner tile number, [1,18] inclusive

Definition at line 148 of file StBbcGeom.h.

TVector3 StBbcGeom::TileCenter ( short tileId )

tells the position of the tile center in STAR Coordinates

Parameters

tileId |tileId| = 1..18 (inner BBC). Sign of tileId tells side. +/- for West/East

Definition at line 107 of file StBbcGeom.cxx.

TVector3 StBbcGeom::TileCenter	(	unsigned short	absValueTileNumber,
		short	eastwest
	)

tells the position of the tile center in STAR Coordinates

Parameters

absValueTileNumber	this is a positive number between 1 and 16, inclusive
eastwest	<=0 for East, >0 for West
