Detailed Description

Class to fix up an ESD object for various small issues.

Input:

• AliESDFMD object - from reconstruction
• Ip z coordinate - from reconstruction
• Reco noise factor - Assumed noise factor used in reconstruction

Output:

• The same AliESDFMD object but modified

Corrections used

• AliFMDCorrNoiseGain if the noise correction is enabled

Histograms

• Change in \(\Delta\) due to noise correction
• Number of channels declared dead
• Change in \(\eta\)

Add dead strips from a script. The script is supposed to accept a pointer to this object (AliFMDSharingFilter) and then call AddDead or AddDeadRegion as needed.

void deadstrips(AliFMDSharingFilter* filter)
{ 
  filter->AddDead(...);
  // ... and so on 
}

Parameters

script

The script to read dead strips from.

		UShort_t	t2
	)

Add a dead region in a detector ring

Parameters

d	Detector
r	Ring
s1	First sector (inclusive)
s2	Last sector (inclusive)
t1	First strip (inclusive)
t2	Last strip (inclusive)
