     This data set consider physical information on velocities
     (km/second) for 82 galaxies reported by Roeder (1990). These are
     drawn from six well-separated conic sections of the Corona
     Borealis region.

_F_o_r_m_a_t:

     A data frame with 82 observations on the following variable.

     '_s_p_e_e_d' a numeric vector giving the speed of galaxies
          ((km/second))
