\caption{Estimated lower limits for the $M/L$s 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.}
