assimilation of special soundings

Does the RUC currently assimilate the special 13 Z sounding that is typically taken from Redstone Arsenal (RSA) (Huntsville region) weekdays? We post RUC soundings (hourly) and 13 Z RSA sounding on our web site for comparison with the microwave profiling radiometer retrieved sounding. I have noticed remarkable similarity between the 13Z RUC and RSA soundings that would imply that the RUC is assimilating the RSA balloon sounding. I am interested in knowing to what degree the RUC and RSA soundings are independent.
