On some analytic properties of a function associated with the Selberg class satisfying certain special conditions

In 2001, M.Rekos described the analytic behavior for a function $f(z)$ connected with the Euler totient function for Im$z>0$ (see (1.2)) imitating the previous research of [1] and [3]. In the present paper, for Im$z>0$ we describe the analytic behavior of the generalized function $f(z,F)$ (see (2.1)), where the function $F$ belongs to the subclass of the Selberg class which has a polynomial Euler product and satisfies some special conditions.
