Comparison of Lyα luminosity and size of the Lyα nebulae detected in this study with Lyα nebulae from the literature. Two square symbols of QSO 1 and 2 indicate two Lyα filters. The LAHs are in cyan color, LABs are in black color and other color symbols are ELANs. All these Lyα nebulae are at high redshift (z > 2). We note that because of the different definitions of sizes, instrument sensitivity, methods, and redshifts, a direct comparison between the size and luminosity of the QSOs in this study with the literature is not possible.
