\tablefoot{``P'' labels indicate spatial correspondence to regions identified by \citet{Johnstone_G11}.  ``e'' indicates where we infer the presence of an embedded protostar based on a 24~$\mu$m detection.  Objects above the horizontal line are located ``on'' the IRDC filament; sources below are~``off.''}
