Notes. The third and forth columns are the total masses and dense masses estimated from the infrared extinction map at AK ≥ 0.1 mag and AK ≥ 0.8 mag, respectively (Lada et al. 2010). The last column is the SFR derived from the YSO observation.The masses and SFRs not marked are from Lada et al. (2010).
