29Note (1): Asterisks mark "deeply embedded" sources with questionable IRAC
30          colors or incomplete IRAC photometry and relatively bright
31          MIPS 24 micron photometry.
32Note (2): Only provided for sources with valid JHK_S_ photometry.
33Note (3): Defined as the slope of the linear least squares fit to the
34          3.6 - 8.0 micron SEDs in log{lambda} F_{lambda} vs log{lambda} space.
35          Extinction is not accounted for in these values.  High extinction can
36          bias Fit to higher values.
