For example, it will serve to direct a physicist or a meteorologist to focus on a problem insuch a manner that his results are pertinent to a biological problem. Columns1, 3, 5, 6, 8, 12, and15 (see Table 1) will contain the field data shown in the right-hand column of Fig. 1. Columns 9, 11, and 14 will contain data on controlled laboratory experiments. Columns 2, 4, 7, 10, and 13 will contain those relations requiring determination of critical values through the use of the data in the other columns. Each column contains a number of boxes that designate general categories of information within the column, and each box in turn contains a listing of specific kinds of information within the particular category. Thus each specific kind of information will be identified by a six-digit code: two digits for the column, two for the box, and two for the listing. It is important to point out that this matrix is dynamic in that it is changed almost daily (andit is important that this flexibility be preserved) by the addition of a column, a box, or a new item in listing. For example, in column 2 there is a box designated “Fireball Phenomenology”; it is expected that this box will eventually become a column. | A complete description of the system and the coding procedures has been reported! and will not be discussed here exceptto indicate that, along with a specific entry, considerable additional information
