(i.e. EWobs

in four extremely clumpy media. We apply some realistic physical conditions of
LAEs to each media:
nIC/nC = 0.00, FF = 0.23,
CF = 0.997 (Rmin = 49 and
Rmax = 64 cells), b = 12.85
km s-1 (i.e. T = 104 K in clumps),
= 1019, 2 × 1020 cm2, and
vexp = 0, 100, 200 km s-1.
fesc(Lyα) is derived assuming an
intrinsic line width FWHMint = 100 km s-1.
From the left to the right, the models are calculated for
= 0, 0.3, 1, 2, 5, 10, 15, and 25.
