Their results are not independent of the HORI 01, HORI 03, and HORI 06 values for q p + q p / e , below. 2 TORII 99 uses the more-precisely-known constraint on the p charge-to-mass ratio of GABRIELSE 95 (see below) to get this result. This is not independent of the TORII 99 value for q p + q p / e , below....
