Notes. Times are in units of JD-2449700. Times of maxima, Gaussian full width at half maximum (gfwhm) and dips were measured with Gaussian fits to the flux curves.

^(a)

The uncertain measurements are noted with a “:” and in Cycle 2, the uncertainty is because the times were interpolated over missing data.

^(b)

Other sets of apparent dips are seen in NIVa as follows: (1) superposed on the maximum at days 32.28,36.20:,39.85, 43.71; and (2) near minima at days 34.10, 37.94:, 41.72, 45.54.
