An optical module that operates stably against temperature changes even in the form of package. The first set of data representative of the relation is adapted on the basis of a measured physiological response of the at least one first user to a rendition of a perceptible content element and values of the at least one variable for characterizing an aspect of the perceptible content element. The linear presegetalin precursors may be derived from other linear presegetalin precursors farther upstream in the biosynthetic synthesis of the segetalin. Cables lengths, which are used for signal transmission, for each antenna device are chosen individually such that a round trip delay time measurement which is based on the transmission signal and received signal of a sought subscriber is used to determine an antenna device via which the received signal sought subscriber is received.
