We compiled an initial sample of young stellar objects (YSOs) on the basis that they were classified as Class II objects in Megeath+ (2012, J/AJ/144/192 and 2016AJ....151....5M) and were located in L1641 (we require that our sample be located below -6° decl., see Figure 1). For this sample, we extracted photometry from the Herschel Orion Protostar Survey (HOPS) open-time key program in 2010 and 2011 (e.g., Stutz+ 2013, J/ApJ/767/36 ; Furlan+ 2016, J/ApJS/224/5 and B. Ali et al. 2018, priv. comm.).(8 data files).
