SECTION 11. OUTPUT PROCESSING INSTRUCTIONS

values are the contributions of the sub-ranges

accumulated into corresponding direction

to the overall weighted value. To obtain the

sectors (bin select input).

average of the weighted values that occurred while the bin select value was within a particular sub-range, the value output to Final Storage must be divided by the fraction of time that the bin select value was within that particular sub-range (i.e., a standard histogram of the bin select value must also be output).

For either histogram, the user must specify: 1) the number of repetitions, 2) the number of bins, 3) a form code specifying whether a closed or open form histogram is desired (see below), 4) the bin select value input location,

5)the weighted value input location (see below), 6) the lower range limit, and 7) the upper range limit.

The standard histogram (frequency distribution) is specified by entering "0" in the weighted value input location parameter. Otherwise, this parameter specifies the input location of the weighted value. When more than one repetition is called for, the bin select value location will be incremented each repetition and the weighted value location will remain the same (same weighted value sorted on the basis of different bin select values). The weighted value location will be incremented if it is entered as an indexed location (key "C" at some point while keying in Parameter 5; two dashes, --, will appear on the right of the display). At the user's option, the histogram may be either closed or open. The open form includes all values below the lower range limit in the first bin and all values above the upper range limit in the last bin. The closed form excludes any values falling outside of the histogram range.

The difference between the closed and open form is shown in the following example for temperature values:

Lower range limit

10°C

Upper range limit

30°C

Number of bins

Closed Form Open Form

Range of first bin

10 to 11.99 deg.

Range of last bin

>28 deg.

A common use of a closed form weighted value histogram is the wind speed rose. Wind speed values (the weighted value input) are
