Table C.1

Best-fitting dX∕dQ values inferred for the single and binary SMC WR stars.

SMC	d X∕d Q	τ_{H env}		M_model
AB		[kyr]		[M_⊙]

Single:
1	≥ 35	≤ 175	≤ 0.56	32
2				18
4				22
9				30
10				20
11				26
12				28
Binary:
3				28
5				50
6	≥ 16	≤ 160	≤ 0.58	50
7				34

Notes. Also displayed are the timescale on which the WR star would blow away its hydrogen-containing layers (τ_{H env} ) and the ratio of τ_{H env} to the helium burning timescale. The last column gives the best fitting current masses.
