Detailed Description

This class calculates the exclusive charged particle density in each for the 5 FMD rings.

Input:

• 5 RingHistos objects - each with a number of vertex dependent 2D histograms of the inclusive charge particle density

Output:

• 5 RingHistos objects - each with a number of vertex dependent 2D histograms of the exclusive charge particle density

Corrections used:

• AliFMDCorrSecondaryMap;
• AliFMDCorrVertexBias
• AliFMDCorrMergingEfficiency

void AliFMDCorrector::DivideMap ( TH2 *  num, const TH2 *  denom, Bool_t  alsoUnderOver = false  ) const

Divide a map with another map. This is a reimplementation of TH1::Divide, but we assume compatible histograms, and the under- and overflow bins are only divided if the third argument is true.

Parameters

num	Numerator. On return contains the result
denom	Denominator
alsoUnderOver	If true, also divide under/overflow bins
