1, We only detected M10A for once from the only two observation. Need confirmation. M10A was confirmed on 20211213.
2, The period of M10B is possible to be its 2nd harmonic. Need more observation to time this pulsar.M10B should have a spinning period of 7.35 ms.
3,  We only detected M71D for once from the only two observation. Need confirmation.M71D was confirmed on 20210917.
4, We detected M3A for twice. Its orbital period is short than the observation time, thus we can obtain its orbital parameters.
