Notes. The first column contains the Loop I SN explosion times t_exp (counted backwards from today). In Cols. 2–5, we give the explosion centres in Cartesian coordinates (x,y,z) with the Sun at the origin, and the resulting distances of the SNe from the Sun d. Columns 6–8 give the masses of each SN progenitor star M_∗, the masses ejected in each SN explosion M_ej, and the corresponding ⁶⁰Fe mass fractions Z. Column 9 lists the parent subgroup of each progenitor star.
