g_tracer_utils::g_tracer_common integer integer g_tracer_utils::g_tracer_common::isd isd Domain extents. Start index of the data domain in the i-direction integer integer g_tracer_utils::g_tracer_common::jsd jsd Start index of the data domain in the j-direction. The following type fields are common to ALL generic tracers and hence has to be instantiated only once. g_tracer_utils::g_tracer_common isd jsd integer g_tracer_utils::g_tracer_commonisd g_tracer_utils::g_tracer_commonjsd
