Notes. Number of progenitors on ZAMS (Nprog), median of the time when the ULX phase commences (med(tULX,start)), and the total (i.e., through the entire history) expected number of ULXs (E[NULX]total). Number in parenthesis inform about the number of simulations with non-zero E[NULX] of specific configuration. Results are present for different configurations of progenitors: A stands for the progenitor of an accretor, whereas D for the progenitor of donor, n stands for stars which do not become part of a ULX, or is a placeholder in case of single stars. p stands for pristine and means that there were no exchanges in a binary before ULX formation. First symbol represents the primary (i.e., more massive star on zero-age main sequence, or ZAMS), whereas the second letter the secondary. Results are divided into First and Second Populations and also between binaries and single stars. Values represent the mean and one sigma error for simulations in which the specific ULX where present.
