Top: light curve for J142508 (automatically classified as EW-type) folded at P = 21568.141 ± 0.002 s. Bottom: OC diagram for J142508 spanning seven years. Blue solid line shows best linear fit (χ2 = 1.28, 252 d.o.f.); green dashed line shows best quadratic fit (χ2 = 1.01, 251 d.o.f.). Visual checks revealed that the apparently good quadratic fit relies in part on the widely-scattered poorer-quality data in the last two observing seasons, and appears inconsistent with the bulk of the closely-grouped observations in the third season (around days 700–800); a sinusoidal fit was therefore preferred. Black long-dashed line shows best sinusoidal fit (χ2< 1.00 using same OC uncertainties as for linear and quadratic fits, 250 d.o.f.), with semi-amplitude 62 ± 7 s and modulation period 710 ± 50 d.
