Addenda (Files 3 - 7 of 9)

The data that most users will find to be of interest are included in File 1, the basic table. However, some volumes contain additional information that may be of use for special purposes. This additional information is included in Files 3 through 7. The following tables describe the format and contents of each of these files. In each case, fields in which data are missing are blank. Although an F or an I format is suggested to give a reading in normal units, the A format may be preferable to distinguish between a blank and a zero.
