List of all members.

Detailed Description

Helper class to help visualizing channel gain evolution over time.

Usage is a 2 step process :

1) emcChannelEvolution ce; ce.produce(run1,run2,opt) will get the (baseline-corrected) gains from run1 to run2 opt is used to determine in which way the baseline is computed (see emcCalibrationDataHelper::getBaseLine())

ce.save("/somedir/") will save the resulting gains into ASCII files

2) emcChannelEvolution c; c.read("/somedir") will read back gains from files. TGraph* g = c.graph(ifem,ichannel) Get a graph of the gain evolution for (ifem,ichannel) tower.

Note that produce(), read(), save() require that the relevant emcDataManager plugin libraries have been loaded. Currently those are (subject to change, though) :

read from Objy : libemcOM.so read from Pg : libemcOMpg.so read/write from/to ASCII files : libemcOMascii.so
