Detailed Description

Class that converts MuDst into PicoDst.

The class allows the conversion from MuDst to PicoDst using several options important options:

Vertex selection criteria (PicoVtxMode)
Since MuDst stored several vertices and PicoDst allows one to keep only one, the vertex selection criteria have been proposed. Currently, next options are available: a) Default - select the first primary vertex (with index = 0) b) VpdOrDefault - uses the Default option at first, and then if BTOF info is available checks for the Vpd option. c) Vpd - checks if BTof info is available then loops over primary vertices and checks if |Vz - VpdVz|<mTpcVpdVzDiffCut. The first vertex that satisfies the cut is selected. d) Mtd - sets the first primary vertex as a default and then loops over all primary vertices. The first one that has at least 2 MTD-matched primary tracks is selected. e) FXT - set the first vertex that was reconstructed in z from 198 to 202 cm along z axis. Default is NotSet. In this case the program execution will be terminated. Has to be explicitly set.
Vertex position (mTpcVpdVzDiffCut)
There is a possibility to cut on the vertex position requiring the difference of vertex position along the beam direction (z) reconstructed in TPC and estimated via VPD by the absolute value to be less then mTpcVpdVzDiffCut. Default is 6 cm.
Saving covariance matrix (PicoCovMtxMode)
In order to store covariance matrix for each track one should specify PicoCovMtxMode with one of two words: a) PicoCovMtxSkip - skip and not write covariance matrix b) PicoCovMtxWrite - store covariance matrices. If covariance matrix does not exist, then it is filled with zeros Default is PicoCovMtxSkip.
Saving BEmc SMD hits (PicoBEmcSmdMode)
To save the BEmc SMD eta/phi hits near a BHT2/3 trigger tower, one should specify PicoBEmcSmdMode with one of two words: a) PicoBEmcSmdSkip - skip and don't write SMD hits for BHT2/3 triggers b) PicoBEmcSmdWrite - save BEmc SMD hits within 1.5 tower radius of every BHT3 Default is PicoBEmcSmdSkip.

Member Function Documentation

void StPicoDstMaker::setCompression ( int  comp = 9)

Sets the compression level for the file and all branches. 0 means no compression, 9 is the higher compression level.

Definition at line 356 of file StPicoDstMaker.h.

void StPicoDstMaker::setSplit ( int  split = 99)

Sets the split level for the file and all branches. Please refer to the ROOT manual ( for more info

Definition at line 355 of file StPicoDstMaker.h.

void StPicoDstMaker::SetStatus ( char const *  branchNameRegex,
int  enable 

Enables or disables branches matching a simple regex pattern in reading mode.

Allows one to disable/enable branches matching a simple regex pattern branchNameRegex when reading picoDst.root files. For example,

StPicoDstMaker::SetStatus("*", 0); // Disables all branches
StPicoDstMaker::SetStatus("Emc*", 1); // Enables branches starting with "Emc"

Note that if the first two characters in branchNameRegex are "St" they will be ignored, i.e. "StBTof*" is the same as "BTof*".
