Top: light curve for J165649 (automatically classified as EB-type) folded at P = 23 775.304 ± 0.003 s. The short period and light curve shape would probably support EW-type classification instead. Bottom: OC diagram for J165649 spanning eight years. Blue solid line shows best linear fit (χ2 = 4.51, 582 d.o.f.); green dashed line shows best quadratic fit (χ2 = 2.14, 581 d.o.f.), which are similarly poor matches to the data. Black long-dashed line shows best sinusoidal fit (χ2< 1.00 using same OC uncertainties as for linear and quadratic fits, 580 d.o.f.), with semi-amplitude 870 ± 9 s and modulation period 2386 ± 11 d.
