Integrating Einstein field equations in observational coordinates with cosmological data functions:: Nonflat Friedmann-Lemaitre-Robertson-Walker cases

In this paper we use the integration scheme for the exact spherically symmetric Einstein field equations in observational coordinates recently developed by Araujo and Stoeger, and input data functions for area distance and galaxy number counts that would be obtained if the universe were exactly represented by nonflat Friedmann-Lemaitre-Robertson-Walker models.
