a All values are corrected for Galactic extinction, adopting the AB from Table 1.
b See Sect. 3 for details. Objects for which the LSB component was modelled by a pure exponential (Eq. (1)) are marked with an asterisk.
c Errors do not include the calibration uncertainties given in Col. 14.
d Decomposition less reliable in this filter (low S/N, or data affected by nearby bright stars).
e K' SBP less deep than J and H; effects on Cols. 10, 11 and 13.
f Small systematic deviations from an exponential LSB profile, likely type V SBP (see notes of caution in Sect. 3).
g Small systematic deviations from an exponential LSB profile, possible type V SBP (see Sect. 4.4, and notes of caution in Sect. 3).
h Detected or likely type V SBP restricts exponential part of LSB fit to low S/N region, preventing robust decomposition in the K band.
i Likely type V SBP, cannot be reliably modelled; exponential LSB fit yields unphysical H band decomposition (see Sect. 4.2).
