Selected transformation

Name: Aratu to WGS 84 (13)

Method: Geocentric translations (geog2D domain)

Remarks: Parameters from Aratu to SIRGAS 2000 (1) (tfm code 5050) assuming that SIRGAS 2000 and WGS 84 are equal within the accuracy of the transformation. Petrobras preferred parameters for all purposes in the area. Replaces tfm codes 15711 and 15734.
