Table 4: Estimated lower limits for the M/Ls of bulge and disk after applying corrections for gas mass and dust extinction. The table lists the component (Col. 1), the estimated gas mass expressed as a percentage of the total mass (Col. 2), the estimated mean J-band extinction (Col. 3), the resulting lower limit for the corrected M/L (Col. 4), and the original (uncorrected) value of the M/L (Col. 5) for comparison.
Component Gas mass J-band extinction $ {(M/L)_{\rm lower}}\ [M_{\odot}/L_{\odot}] $ ${(M/L)_{\rm uncorrected}}\ [M_{\odot}/L_{\odot}] $
Disk $ \leq$7% $\sim$ 0.5 mag 0.4 $0.7\pm 0.4$
Bulge $ \leq$20% $\sim$3.0 mag 0.02 $0.4\pm 0.2$
