We measure the stellar mass function of X-ray–selected galaxy clusters from the eROSITA eFEDS survey using WISE W1-band photometry. After correcting for masking and incompleteness, we derive luminosity functions and convert them into stellar mass functions with a mass-to-light ratio. This pipeline is extendable to future all-sky cluster catalogs.
