Notes. ‘LTG’ refer to the samples of complete ULXs in spiral galaxies. ‘LTG39’ stands for the samples of spiral galaxies having Llim < 1039 erg s−1; they correspond to the classical, non-renormalised XLF. n39, α1, α2 and log(Lbreak) are the amplitude, faint-end slope, bright end slope and break luminosity of the broken power-law model, respectively. See the text for more details.
