Caption: Figure 4.
Normalization factor applied to each row to account for relative sensitivity to diffuse/extended sources compared with that in Row 16, which has been extensively calibrated, using a 3600 s dark sky observation. Detector rows 0–5 and 27–31 are outside of the FOV of the slit and are therefore set to 1. The normalization array shown in this figure is applied to each row in the scan observations to calculate the Lyα flux across the Alice FOV.
