number of active beetles, actually recorded in that quarter-month

estimate of active beetles, inferred* from adjoining date ranges
actual count > 4 (median)
actual count <= 4 (median)
 *Inferred when a site has counts of active beetles for each of two consecutive periods (date ranges), one finishing and the other starting in the same quarter-month.
The count estimate is assigned to that quarter-month and calculated as the lower of the two total beetle counts, divided by the number of quarter-months in its date range.
