Table 2.

Results of the time-delay and differential dust extinction retrieval for each investigated S/N and color curve scenario.

Δt_true = 16.3 days	Case 1: high S/N		Case 2: low S/N		Case 3: low S/N, 35% data loss
(A_V, B − A_V, A)_true = 0.2 mag	Case 1: high S/N		Case 2: low S/N		Case 3: low S/N, 35% data loss
u − g	16.30 $_{- 0.14}^{+ 0.14}$ $^{+0.14}_{-0.14}$ days	0.20 $_{- 0.02}^{+ 0.02}$ $^{+0.02}_{-0.02}$ mag	16.3 $_{- 3.6}^{+ 3.2}$ $^{+3.2}_{-3.6}$ days	0.2 $_{- 0.8}^{+ 0.7}$ $^{+0.7}_{-0.8}$ mag	16.9 $_{- 5.0}^{+ 5.7}$ $^{+5.7}_{-5.0}$ days	0.4 $_{- 1.1}^{+ 1.3}$ $^{+1.3}_{-1.1}$ mag
u − g, u − r	16.29 $_{- 0.08}^{+ 0.08}$ $^{+0.08}_{-0.08}$ days	0.20 $_{- 0.01}^{+ 0.01}$ $^{+0.01}_{-0.01}$ mag	16.3 $_{- 0.8}^{+ 0.8}$ $^{+0.8}_{-0.8}$ days	0.2 $_{- 0.1}^{+ 0.1}$ $^{+0.1}_{-0.1}$ mag	16.4 $_{- 1.0}^{+ 1.0}$ $^{+1.0}_{-1.0}$ days	0.2 $_{- 0.1}^{+ 0.1}$ $^{+0.1}_{-0.1}$ mag

Notes. The time delays Δt are listed on the left and the dust extinction A_V, B − A_V, A on the right of each case.
