Each report, with all of the parameters given in Table I. encoded, occupies one standard IBM Hollerith card. Rapid and consistent coding of reports is accomplished with a set of tables which closely define the characteristics of each parameter of the source report and convert that information into numerical data. The resulting punched card contains most of the information in the source report, but now in a form which can be analyzed by the computer.

All of the reports encoded using the above system are coarsely filtered, as described in earlier papers, to eliminate observations which have too little information content to be usable or those which include details strongly suggesting a known cause. In addition, reports which do not include a date are eliminated from the computer file, since such information is required by the operating program to unambiguously identify the report.

It should be noted that the APDF format allows the deletion of any unknown parameters, with the exception of the year, month, day and, at least, the approximate location of the observation. Some of the reports gathered during the last four year were deleted from the computer file as a result of the above constraints. In some cases, the deleted reports were of reasonably good quality, lacking only a date.

SUMMARY OF SELECTED DATA GATHERED SINCE 1972

Total Reports

Item	Phenomenon	Percentage
1	Nocturnal Lights	43 (78.1%)
2	Daylight Objects	3 (5.5%)
3	Close Encounters (CE-1) 6 (10.9%) (	43 (78.1%)
4	Others	(5.5%)

Figure I. is a plot of the number of reports received over the four year study period versus the month Or the year. Figure II. graphs the number of reports versus the hour of the day, over the four year period.

Further analysis of these data indicates, among other things, that there were nine photographs made, four cases involving the scouting of a terrestrial vehicle, at least one case involving electromagnetic effects, one case of a "beeping" sound and one case in which animals were affected.
