AbstractThe color-stellar mass-to-light ratio relation (CMLR) is a widely accepted tool for estimating the stellar mass (M-*) of a galaxy. However, an individual CMLR tends to give distinctM(*)for a same galaxy when it is applied in different bands. Examining five representative CMLRs from the literature, we find that the difference inM(*)predicted in different bands from optical to near-infrared by a CMLR is 0.1 similar to 0.3 dex. Based on a sample of low surface brightness galaxies that covers a wide range of color and luminosity, we therefore recalibrated each original CMLR inr,i,z,J,H, andKbands to give internally self-consistentM(*)for a same galaxy. Theg-ris the primary color indicator in the recalibrated relations, which show little dependence on red (r-z) or near-infrared (J-K) colors. Additionally, the external discrepancies in the originally predicted gamma(*)by the five independent CMLRs have been greatly reduced after recalibration, especially in the near-infrared bands, implying that the near-infrared luminosities are more robust in predicting gamma(*). For each CMLR, the recalibrated relations provided in this work could produce internally self-consistentM(*)from divergent photometric bands, and are extensions of the recalibrations from the Johnson-Cousin filter system by the pioneering work of McGaugh & Schombert to the filter system of the Sloan Digital Sky Survey.
