• We have been measuring the ion temperature by means of a retarding potential analyzer (RPA) aboard the sounding rocket whose velocity is comparable to the ion thermal velocity. In order to determine the ion temperature T_i from the RPA data, an optimum fitting procedure is used. It was believed that the deduction of T_i at low ram velocity by computer methods without assumption of ion mass number was impossible. This paper deals with an improved accurate fitting procedure to obtain T_i and mixed ion mass number. We advocate the usefulness of the improved error evaluation function. We also show the actual data analysis procedure.
