output	What to return as values in csv and xml formats. optional	output	deployed	"f" = returns frequency data A year's data is divided into 48 time periods, 4 time periods for each month. These periods are 7 days each for period one through three, with period four containing all remaining days of the month (i.e., 7 to 11 days) An empty field represents no data available for that time period A field containing a "P" indicates the bird was reported on a checklist, but the checklist was not reporting all species. A field containing a "0" indicates that checklists were submitted for that time period, but that the species was not reported. A field containing a numeric value greater than 0 and less than or equal to 1 indicates the frequency of positive sightings for that time period.
