We present weak lensing measurements for the intracluster medium (ICM)-selected cluster sample RASS-MCMF, identified by applying the Multi-Component Matched Filter (MCMF) algorithm to the second ROSAT All-Sky-Survey (RASS) source catalog (2RXS). A subset of 171 clusters out of 8449 from the RASS-MCMF sample overlaps with the Hyper Suprime-Cam (HSC) survey footprint, enabling weak lensing analyses. The redshift of these clusters ranges from 0.1 to 0.75. Using the HSC data, we model the shear profiles and perform weak lensing mass calibration for the RASS-MCMF clusters within the HSC footprint.
