Notes.
Galactic extinction corrected flux in units of 10-17 erg s-1 cm-2. The flux is quoted as measured in the X-shooter spectrum (without correction). The flux error is statistical only, and does not contain the error of the absolute flux calibration.
The given correction includes the matching factor to broad-band photometry, stellar Balmer absorption if applicable, and reddening according to the Balmer line ratio. These factors are not independent. In particular it was assumed that [N ii] and Hα, for example, have identical values (except for the Balmer absorption).
