// a constexpr static bit map must be defined and sent as template argument
// The user has to include in this bit map all the tables needed in analysis, as defined in VarManager::ObjTypes
// Additionally, one should make sure that the requested tables are actually provided in the process() function,
// otherwise a compile time error will be thrown.
// This is a temporary fix until the arrow/ROOT issues are solved, at which point it will be possible
// to automatically detect the object types transmitted to the VarManager
