In a previous work [Informes Técnicos Ciemat 1201, CIEMAT, March 2010], the Astra shell [Tech. Rep. IPP 5/98, Max Plank Institut für Plasmaphysik, Garching, February 2002] was extended by the addition of several peripheral codes that increase the capabilities of transport calculations for plasmas of the TJ-II device (Laboratorio Nacional de Fusión, CIEMAT). Here we document the inclusion of equilibrium calculations and the evolution of the rotational transform, developed later on, informing as well about the calculation methods and providing a short guide for the user.
