Abstract
A sample of 224 IRAS sources was obtained from the IRAS co-added images in the dark cloud L1641. Most of these sources were observed in CO and 13 CO (J=1-0). The 122 sources within L1641 are likely to be embedded young stellar objects (YSOs). The sources outside L1641 are mostly extended far-infrared cirrus emission. The infrared and millimeter data were used to search for the indicators of the evolutionary state of YSOs. The IRAS sources associated with CO outflows are significantly different from the nonoutflow sources because those with CO outflows have higher 13 CO column densities, higher far-infrared luminosities, and cooler IRAS color temperatures
