rate_stream::is_real_rate Return the fact that a rate stream is a "real" rate stream. Usage: rv = strref->is_real_rate() Notes: This method must be overridden in any stream class that is not a true rate stream (i.e. streams that have units other than particle fluxes, and streams which can't be converted between flux and count rates). Any rate stream class returning zero MUST support the unit keyword to get_idf_info History: Original: 10/7/00; SJT
