A. The Nordic format

Free columns are included for two purposes:

  1. To obtain a readable format
  2. To have some space for possible future extensions

Here are examples, top 3 lines for positioning only.

ID and hypocenter agency. The magnitudes on this line will then be associated with the main

by earlier versions. However, an UPDATE would fix that.
  ** Long phase names: An 8 character phase can be used in column 11-18. There is then not
room for polarity information. The weight is then put into column 9. This format is recognized
