Left: JCMT/SCUBA 850-μm map of Serpens Main region with numbers corresponding to SMM sources as classified by Davis et al. (1999). Contours are [3, 6, 12, 20, 40] × 0.50 mJy arcsec⁻². Beam of the JCMT observations of 1.′′is indicated in the bottom-left corner. Right: ALMA 1.3 mm continuum of targeted protostars. For SMM9, field contours are [3, 6, 9, 12] × 0.53 mJy beam⁻¹ and for SMM1 field contours are [3, 4, 5, 6, 9, 15, 40, 50] × 0.62 mJy beam⁻¹. Synthesized beams of the ALMA observations are 0.′′35 × 0.′′33 for the SMM9 field and 0.′′36 × 0.′′30 for the SMM1 field.
