Notes. Detection limits computed for circular apertures with a size of 100 arcsec². The upper-limit SB measurement based on placing apertures is indicated as ${\mu }_{\lim }^{\mathrm{aperture}}$. For galaxies with significant variation in the sky-σ image, we list the limit as derived from the whole field versus the field cropped to a region of low sky-σ (the latter is stated in brackets). The uncertainties of the detection limits come from the calibration process from luminance to the r-filter. Calibration errors and uncertainties from background noise (based on the aperture measurements) were propagated for the measurement of the stream SB, μ_stream.
