Pass List Format

The Pass List file will be saved as a text file named PassList.txt in the WXtrack Results folder.  A sample from the current pass list format is shown below.  Note that I regard this format as internal to the program, so I make no guarantee that the format will remain unchanged.  In particular it is likely that I will add a four digit year prefix at some point in the future.

The pass list comprises a number of columns of variable width.

1 Time in UTC, may include four digit year prefix and two digit seconds suffix
2 Satellite direction at mid-pass
3 Satellite longitude at mid-pass
4 Pass duration in seconds
5 Satellite name, may include spaces

Suggestions for coping with differing versions

Look for the first space, to determine the width of the first column.  If this is eight characters you have a version prior to 1.6 with no seconds data, or mid-pass longitude.

If the first four characters numerically exceed 1231 (December 31), they are a four digit year.
