Table 5: Parameters for the single component model to SGP_8884 before convolution with the instrumental profile. We also include the parameters for the single component and the two double component models of the previously confirmed LAE S11_5236 (Westra et al. 2005). These parameters differ slightly from Westra et al., since we have subsequently corrected the spectrum of S11_5236 for slit-losses.
