Shown here are lower (to-the-right pointing triangles) and upper (to-the-left pointing triangles) limits on the position of the wind termination shock based on Eq. (1), assuming A _⋆  = 1 in all cases (Table 3). Note that GRB 060614 is a much debated burst (see Sect. 3.1.1). The step curves are the cumulative distributions to the lower limits up to which a wind profile is identified and upper limits after which a constant density medium (ISM) agrees with the data.
