31 | * @class AliHLTEveHistoMerger | |
32 | * Implementation of the component to read histograms from other | |
33 | * components and add, divide etc. | |
34 | * The component implements the interface methods of the @ref AliHLTProcessor. | |
35 | * | |
36 | * The component has the following component arguments: | |
37 | * | |
38 | * -sum-noise-histograms Loops over the output of TPCNoiseMap and sums the partition histograms | |
39 | * They are sorted per TPC side. | |
40 | * | |
41 | * -sum-krypton-histograms Loops over the output of the krypton CF and sums the histograms | |
42 | * (it will become obsolete, when the next option does all the work) | |
43 | * | |
44 | * -use-general It will become the standard general option for summing histograms | |
45 | * | |
46 | * -ignore-specification It ignores the last part of the histogram name, if it has | |
47 | * the form "_Slice_%.2d%.2d_Partition_%.2d%.2d, minSlice, maxSlice, minPartition, maxPartition". | |
48 | * It keeps the first part of the hist name and uses it to name the summed histogram. | |
