+// AliPHOSSurvey1 class is survey "reader" class, based on AliSurveyObj class.
+// The first ctor parameter is a survey file's name.
+// Now it's a "local" file, later, when AliSurveyObj will be modified,
+// survey files can be somewhere else.
+// The second parameter is a prefix, for example "T1_" or "T2_", it's used to select
+// survey (T1_ == data from 08.09.2006 and T2_ == data from 11.09.2006).
+// The survey data is available from http://dcdb.cern.ch/surveydepot-production/
