Notes. The first column is the reference (l′), Cols. 2–7 are the corresponding number of GCs (
), the maximal number of observed regions or bins (
), the size on the sky corresponding to the slit size, the wavelength range (Δλ), the number of the integrated spectral energy distributions (Nspe(l′)), and spectral resolution. The data provided by U17 is the spectra in the UBRI passbands (last four rows).
