Notes. The details of the X-ray pulsators, including the positional information, XMM-Newton detection ID, and the source association in the 4XMM catalog. The source XMMU J173029.8–330920, XMMU J175441.9–265919, and XMMU J180140.3–234221 are the first time detected by XMM-Newton in our ongoing Heritage survey of the Galactic disk. We also searched for Swift-XRT and Chandra counterparts of these two sources, but no counterparts were found. The PGaia represents the probability of spurious association with a Gaia source.
