Octal code for radio surveys in which this pulsar has been detected; each survey has a unique code, the listed code being the sum of the codes of all the surveys which detected the pulsar. e.g., a value of 111 = 100 + 10 + 1 means that it was detected in the Molonglo 1 (1), Molonglo 2 (10), and Jodrell Bank 2 (100) surveys. The full key is given below:
