Light curves of V582 Lyr in the BVRI bands observed on 2016 July 04, and of V1016 Oph on three days (2018 April 23, 27 and May 3), with gray squares (□) for the B band, green circles (◦) for the V band, a blue triangle(△) for the R band, and an inverted purple triangle (﹩\unicode{x025BF}﹩) for the I band. The magnitude difference between the comparison and check stars is in the lower panel. The red solid lines are the theoretical light curves for the spotless model, where the value of Σω_i(O – C)﹩{}_{i}^{2}﹩ is 0.8444 for V582 Lyr and 2.1410 for V1016 Oph. The yellow solid lines are for the theoretical model with one spot, where the value of Σω_i(O – C)﹩{}_{i}^{2}﹩ is 0.6380 for V582 Lyr, and the dashed black lines are for theoretical model light curves with two spots, where the value of Σω_i(O – C)﹩{}_{i}^{2}﹩ is 0.2933.
