SEDs of YSOs in Gy 3-7 well-fitted with Robitaille (2017) models with envelopes. The best fit model is indicated with the black solid line and gray lines show the YSO models with χ² between and , where n is the number of data points and F is a threshold parameter which we set to 3 (Sewiło et al. 2019). Filled black circles are valid flux values with uncertainties. The values of a reduced χ² and interstellar visual extinction for the best-fit model are indicated in the plots. Appendix C shows the SEDs for the remaining YSOs in Gy 3–7.
