The Morlet-6 wavelet (sine-cosine pair extending over 6 cycles and confined by a Gaussian) applied to the HD 37806 data sampled at the MOST orbital period of 0.07046 d. The light gray areas correspond to stronger power. Edge effects influence the wavelet transform beyond the broken lines. Note that the phase information for this complex-function transform has been disregarded by using the power of the transform. The missing orbital data were interpolated at two points marked by tick marks along the lower horizontal axis, but no detrimental effects appear to be present there.
