Notes. For all MT sequence models α = 0. A full list of all MT sequences found is available at the CDS. The parameters at the crossing period P_orb correspond to those the binary system is believed to have at present.

^(a)

Fraction of transferred mass lost from the BH.

^(b)

BH mass.

^(c)

Donor mass.

^(d)

Orbital period.

^(e)

Fraction of hydrogen in the core of the donor.

^(f)

Age of the donor.

^(g)

BH spin.

^(h)

Luminosity of the donor.

^(j)

Fraction of element H left in the core.

^(j)

Total weight for MT sequence from Eq. (14).

^(k)

Time spent around the observed orbital period.
