+\subsection mapping_s3_sub11 ManuSerialToBin.dat
+
+Lines starting with # are comments.
+
+Contains the manu serial number with their associated bin number, injection and calibration gain.
+
+To compare the bin number with the serial in the CDB database you can run the macro:
+
+<pre>
+AliMpCDB::LoadDDLStore2();
+.L $ALICE_ROOT/MUON/mapping/macros/MUONCheckManu.C+
+MUONCheckManu(10, kFALSE);
+</pre>
+
+The function has two parameters, the first is the number of the chamber (zero mean all chambers).
+The macro can create a set of histogramms with the different gain distributions stored into a root file
+(second parameter).
+
+Two files a generated: one with the list of manu per detection element with their associated bin and gain
+value, the other with the bad, strange or unidentified serial number.

+\section mapping_s4 Data files in mapping/data_run
+
+The directory data_run in $ALICE_ROOT/MUON/mapping contains files
+with data which are expected to change during experiment.
+At present time, there are only files with manu serial numbers:
+
+\subsection mapping_s4_sub1 deName_manu_dat.dat
+
+Contains the list of manuIds and their serial numbers.
+
+<pre>
+# Id bp/nbp serial
+1 bp 4615
+2 bp 4616
+...
+</pre>
