There is a slight $\eta$-dependence

You can either parametrize it via $z$ readout segmented as

or you can add calculation for eta variable to

EICrecon/src/algorithms/calorimetry/CalorimeterHitReco.cc

Lines 118 to 127 in 5e39885

	std::function hit_to_map = [this](const edm4hep::RawCalorimeterHit &h) {
	std::unordered_map<std::string, double> params;
	for(const auto &p : id_spec.fields()) {
	const std::string &name = p.first;
	const dd4hep::IDDescriptor::Field* field = p.second;
	params.emplace(name, field->value(h.getCellID()));
	trace("{} = {}", name, field->value(h.getCellID()));
	}
	return params;
	};

and use that

@veprbl Thank you approving my pull request. I'm also appreciative of your comments. I'll refer to the slight eta dependence for my further sampling fraction and reconstruction studies.
