b) seven of their D, A, and B code pulses agree and at least one of their C code pulses agrees. 3.1.2.8.2 The test for code agreement among the three replies is made individually for each of the reply pulse positions. This test is based on the presence of code pulses alone; agreement occurs for a given reply pulse position if all three replies are detected with ONE in the position or all three replies are detected with a ZERO in that position. The confidence associated with those pulse detections does not affect agreement. 3.1.2.8.3 The confidence flag for a reply pulse position is set “low” whenever there exists another received reply (either real or phantom) that could have had a pulse within ±0.121 microsecond of the same position. Otherwise, the confidence flag is set “high”. 3.1.2.8.4 When agreement among the three replies does not occur for a given reply pulse position, the initial track pulse code estimate for that position is based on the values of the individual pulse codes and the confidence flags associated with those pulse codes in three replies. 3.1.2.8.5 When agreement fails for a given pulse position, the rules for estimating the initial track code for that position are based on the principle that “low” confidence ONEs are suspect. The rules are as follows:
