Notes.
is the minimum number of data points per dither position before sigma clipping.
is the number of standard deviations used in clipping the data points. Npar is the number of parameters fitted, plus the number of omitted data points (Np in Eq. (4) includes both of these). Items in the last two columns (unbiased estimates of the standard deviation of the residuals and occultation depth) refer to the OOE = 1 normalization as described in Sect. 2.
