We study the conditions under which a function satisfying a weighted Morera property for all hyperbolic circles of a fixed radius is holomorphic. We show that one of such conditions is the restriction on a speed of decrease of the difference between the function and its Cauchy type integral.
Keywords: Cauchy integral formula; holomorphy tests; Legendre functions; hyperbolic plane.
