_D_e_s_c_r_i_p_t_i_o_n:

     A numeric vector giving the Third Series of measurements of the
     passage time of light recorded  by Newcomb in 1882. The given
     values divided by 1000 plus 24 give the time in millionths of a
     second for light to traverse a known distance. The ``true'' value
     is now considered to be 33.02.
