Parameters
eta1Value of $ \eta $ in one end/edge/boundary of the valid $ \eta $ range.
eta2Value of $ \eta $ in the other end/edge/boundary of the valid $ \eta $ range.
resThe resolution.

Construct an instance of EtaDepResElement from the lower limit, upper limit, and a string which encoded the resolution. The constructor will determine automatically which one among the two input $ \eta $ s is the lower (upper) limit.

Parameters
eta1Value of $ \eta $ in one end/edge/boundary of the valid $ \eta $ range.
eta2Value of $ \eta $ in the other end/edge/boundary of the valid $ \eta $ range.
