Physical properties of A68-HLS115 from Sklias et al. (2014) and Dessauges-Zavadsky et al. (2015).

Parameters	Values
L_IR (10¹² L_⊙)	1.12 ± 0.06
L_UV (10¹⁰ L_⊙)	2.17 ± 0.20
M_* (10¹⁰ M_⊙)
SFR_SED (M_⊙ yr⁻¹)
SFR(IR+UV) (M_⊙ yr⁻¹)	118 ± 6
sSFR = SFR_SED/M_* (Gyr⁻¹)	3.12
A_VIR/UV^a
T_dust (K)	37.5 ± 1
z_CO	1.5859
F_CO^b (Jy km s⁻¹)	2.00 ± 0.30
M_gas^c (10¹⁰ M_⊙)	7.83
f_gas	0.75 ± 0.15

Notes. The values have been adjusted to the Chabrier IMF and corrected for a lensing magnification of μ = 4.6 (see Sect. 4.1).

^(a)

A_V is obtained from the ratio of L_IR over L_UV as discussed in Sklias et al. (2014) and Schaerer et al. (2013).

^(b)

Observed CO(2–1) line integrated flux.

^(c)

M_gas is obtained assuming a CO-to-H₂ conversion factor of 4.36 M_⊙/Kkms⁻¹ pc².
