The Kill Edit Instruction Format

The kill instruction causes a processing program that's capable of recognizing such an instruction to omit the indicated data. The format is very rigid. The kill instructions appear in a file that may contain other types of editing instructions. Each instruction occupies one line. Each line contains the following (Fortran style formats are given after each item):

a satellite ID (A1, I2)
starting station sequence number (1X, I2)
ending station sequence number (1X, I2)
starting frequency identifying number (1X, I2)
ending frequency identifying number (1X, I2)
starting epoch sequence number (1X, I6)
ending epoch sequence number (1X, I6)
the instruction identifier value (1X, F12.0)
the number of epochs affected (1X, I4)
a short but informative message (1X, A32)

Note that the evolution of the data processing programs has resulted in the station sequence number always being equal to "1". A sample file looks like:

 28  1  1  1  2     14     14       -9999.    1 Vupos kill 2003-063  0:36:30
