This is the revised catalogue of 247 X-ray groups of galaxies in the 2 square degree COSMOS field with M200c = 8x10^12 - 3x10^14 M_sun at redshift range of 0.08 <= z < 1.53. The main revisions are on the group X-ray centre using the combined data of the XMM-Newton and Chandra and the redshift based on the COSMOS2015 photometric redshifts catalogue (Laigle et al. 2016) and the COSMOS spectroscopic redshifts catalogue (Hasinger et al. 2018).
