◆ LEADING_BETA_SHAPE

const double LEADING_BETA_SHAPE = 0.175

Tuning parameter for seasonal weights, between 0 and 1, where lower numbers give greater weight to seasonal photos.

The leading beta shape controls dates that are approaching and the trailing beta shape controls dates that just passed. When these are set to 0.175 and 0.31, respectively, about one quarter of the photos are from the upcoming week in prior years and about one quarter of the photos are from the preceding month in prior years.
