7、anatory note on the presentation of information in the following Annex The information is set out in four columns: - The name of the data appears in the first column. Their exact definitions may be found in Appendices 3 and 4 of the Radio Regulations and in IFRB Circular No. 536. - The type of data

8、appears in the second column; this may be numeric (NUM), alphanumeric (ALJ) or graphic (GRA). - Theformat of the data appears in the third column. This format is as follows: Alphanumeric data are given either in the form X(N), where N is the number of characters, or else showing the exact position o

9、f each lype of character. (For example: Geographical coordinates of the earth station: 999 x 9999 - 99 x 9999); Integral numerical data are given either in the form 9(N), where N is the number of characters, or m an expanded form, (For example: i: 999 represents a three figure integer which may be e

10、ither positive or negative); Decimal numerical data are given in the format 9(NIi), 9(N2), where NI is the number of characters of the integer number and N2 is the numbex of characters of the decimal fraction. They may somethnes be given in an expanded form. (For example: f 9.99 represents a positiv

11、e or negative decimal number consisting of a single-figure integer and a two-figure decimal fraction); Where necessary the appropriate unit symbols appear after the data; For graphical data a reference to the corresponding Annex is given in the fourth column. - Any supplementary remarks on the data

12、are given in the fourth column. The expression “refer to corresponding annex“ which appears in the “remarks column“ means that for exchanging the corresponding data it is necessary to provide them by an annex that could consist of a graph, a table, or a formula.
