Statistics of the spectra. Top: Number of spectra per star. The star index is sorted in ascending order of the total number of spectra per star (Ntot, black), and for equal Ntot in ascending order of the number of BESO spectra (red). Bottom: Cumulative fraction of the number of spectra for Cs and SBs, zoomed in to the range 0–30. The dotted lines mark the median; Cs have statistically (about 9/12) fewer spectra than SBs.
