Minimum 10 fits from the defined best fit criteria was required to calculate the weighted mean values. Note (2): Class -- 0: deeply embedded; 1: Class I; 2: Class II; F: Flat spectrum; 3: transition disks. -------------------------------------------------------------------------------- 1 * SSTOERC_G049.4183+0.3211 290.252258 14.780608 1.14 0.43 6.84 0.94 3 1 1.74 0.06 2 * SSTOERC_G049.4821-0.3507 290.895782 14.520227 4.12 1.58 8.65 1.27 1 1 2.55 0.2 3 * SSTOERC_G049.3793-0.256 290.759369 14.474311 2.97 0.99 10.49 1.22 0 1 2.02 0.36 4 * SSTOERC_G049.3884-0.2634 290.770569 14.478874 1.08 0.85 8.79 0.70 2 F 0.29 0.9 5 SSTOERC_G048.8743-0.5188 290.752411 13.905082 4.06 1.50 8.72 1.29 1 1 2.12 0.12 6 SSTOERC_G048.9022-0.2734 290.54303 14.045395 2.22 0.63 7.47 0.73 1 1 2.35 0.12 7 SSTOERC_G048.9916-0.3143 290.623596 14.104997 5.15 0.12 9.44 0.09 2 1 1.02 0.18 8 SSTOERC_G049.0693-0.3164 290.663391 14.172537 1.09 0.06 6.28 0.09 2 F 0.11 0.21 9 SSTOERC_G049.1138-0.2963 290.666656 14.221247 1.15 0.0 6.37 0.00 2 1 0.35 0.08 10 SSTOERC_G049.0327-0.3431 290.66983 14.127697 5.15 0.0 9.45 0.00 1 1 0.85 0.17 11 SSTOERC_G049.2213-0.3354 290.754608 14.297651 1.17 0.13 6.39 0.21 2 1 2.02 0.27 12 SSTOERC_G049.3820-0.2563 290.760986 14.476582 1.16 0.21 6.36 0.33 2 1 0.95 0.17 13 SSTOERC_G049.3800-0.2696 290.772064 14.468561 5.39 2.36 8.7 1.47 1 1 2.81 0.28 14 SSTOERC_G049.5688-0.2725 290.866852 14.633584 1.13 0.15 6.33 0.16 2 1 0.45 0.24 15 SSTOERC_G049.4252-0.354 290.870911 14.468496 1.61 0.59 6.85 0.66 1 1 2.12 0.18 16 SSTOERC_G049.4491-0.3611 290.889069 14.486297 1.20 0.31 6.43 0.30 2 1 0.63 0.24 17 SSTOERC_G049.4885-0.3628 290.909912 14.520178 9.47 2.45 11.38 1.1 1 1 2.39 0.13
