(2007); CDF88 = reflection nebulae study by Chavarria-K. et al. (1988); GFM = Chandra survey by Giardino et al. (2007); EC = Eiroa & Casali (1992); SVS = Strom, Vrba, & Strom(1976); KOB = ISO survey by Kaas et al. (2004); 2MASS = 2Micron All-Sky Survey. Note (2): Years that sources were observed: 2006, 2008, 2009, 2010 and 2011. Telescopes used for observation: M for the MMT, W for the WIYN telescope, and B for the Bok telescope. Note (3): g = Spectral types from Winston et al. (2009) or Oliveira et al. (2009). Note (4): poss = possibly. Note (5): When a value is present, its associated EW value in the previous column is the minimum value observed. Note (6): h = Photometry from 2MASS: J replaces V and (J-H) replaces (V-R). f = Source has a known companion, not resolved in our photometry. Note (7): Spectral region observed and number of observations in each wavelength range: B stands for blue and R for red (see text for exact wavelength range for each telescope/set of observations). -------------------------------------------------------------------------------- Photometric Standards SCB 41 08B,09W,10W 18 28 58.4 01 10 59.7 A9-F2 F1 no 5.5 11.16 0.81 0.50 3B, 3R Photometric Standards SCB 43 08B,09W,10W 18 29 08.0 01 05 25.4 F5-F9 F6 no 2.8 11.62 0.79 0.45 3B, 3R Photometric Standards BD+01 3686/SCB 47 08B,09W,10W 18 29 27.6 01 12 56.8 F2-F6 F4 no 4.0 11.03 0.68 0.39 3B, 3R Photometric Standards BD+1 3693/SCB 60 08B,09W,10W 18 30 10.4 01 19 33.7 A5-A8 A7 poss 8.0 10.53 0.53 0.33 3B, 3R Photometric Standards SCB 67 08B,09W,10W 18 30 35.0 01 20 21.9 A9-F2 F0 no 4.8 12.19 0.74 0.44 1B, 3R Photometric Standards SCB 70 08B,09W,10W 18 30 54.5 01 12 52.7 F3-F6 F4.5 no 3.7 11.99 0.86 0.52 2B, 4R Photometric Standards SCB 72 08B,09W,10W 18 30 56.2 01 14 15.8 F6-F8 F7 no 3.0 12.45 0.88 0.54 2B, 3R Candidate YSOs 09W,10W 18 28 55.5 01 12 18.4 K1-K3 K2 no 1.0 14.26 1.16 0.70 1B, 2R Candidate YSOs 10W,11M 18 28 55.6 01 27 03.5 G5-K0 G7 no 1.9 17.93 1.79 1.11 2R Candidate YSOs 11M 18 28 56.0 01 10 34.0 K0-K2 K1 no 1.3 19.26 2.43 1.99 1R Candidate YSOs 11M 18 28 56.1 01 19 53.7 G5-K0 G9 no 1.5 19.61 1.68 1.37 1R Candidate YSOs SCB 40 08B,09W,10W 18 28 56.2 01 06 27.6 F7-G0 F9 yes 2.6 11.32 0.89 0.48 2B, 2R Candidate YSOs 09W,10W,11M 18 28 56.3 01 20 41.3 A3-A6 A5 no 5.2 16.30 1.57 1.02 1B, 3R Candidate YSOs 10W 18 28 56.5 01 23 55.5 M0-M1 M0 no 0.90 16.77 2.66 1.78 1B, 1R Candidate YSOs 10W,11M 18 28 56.7 01 18 49.9 K6-K8 K8 no < 0.52 17.71 1.70 1.11 1B, 2R Candidate YSOs 10M,11M 18 28 56.8 01 21 03.2 K3-K4 K3 poss 0.80 18.54 2.06 1.46 2R Candidate YSOs 11M 18 28 56.9 01 17 51.0 F7-G3 G0 poss 2.7 19.66 1.88 1.76 1R Candidate YSOs 11M 18 28 57.0 01 26 20.7 K2-K3 K3 no 0.82 18.13 2.27 1.36 1R Candidate YSOs 10W,10M,11M 18 28 57.3 01 12 15.8 A5-F1 F0 no 6.2 17.57 1.67 1.12 1B, 3R Candidate YSOs 10M 18 28 57.3 01 13 03.0 K4-K6 K1 yes < 2.1 19.92 2.02 1R Candidate YSOs 10W,10M,11M 18 28 57.4 01 25 15.3 F4-G0 F7 no 3.4 16.85 1.70 1.01 1B, 3R Candidate YSOs 10M 18 28 58.2 01 26 30.6 G5-K2 G9 no < 1.9 18.62 2.17 1.24 1R Candidate YSOs 09W,10W,10M 18 28 59.0 01 25 55.5 F4-F6 F5 no 3.3 15.46 1.57 0.86 1B, 3R Candidate YSOs 10M 18 28 59.3 00 58 11.5 M0-M4 M2III no < 5.6 19.17 1.68 1.24 1R Candidate YSOs 10M 18 28 59.3 01 22 03.4 K0-K4 K2 no < 1.3 18.89 2.58 1.46 1R Candidate YSOs 10M,11M 18 28 59.9 01 19 05.6 F0-F5 F3 yes 4.7 19.09 1.98 1.42 2R Candidate YSOs 10W,11M 18 29 00.0 01 06 14.4 A9-F5 F4 no 4.0 17.52 1.96 1.34 1B, 2R Candidate YSOs 10W,11M 18 29 00.5 01 25 27.0 G9-K2 K0 no 1.2 17.21 2.24 1.36 2R Candidate YSOs 09W,10W,11M 18 29 00.7 01 27 26.1 F4-G2 F7 no 3.4 16.17 1.63 0.95 1B, 3R Candidate YSOs 10M 18 29 00.9 01 19 48.8 F5-G9 G3 no < 1.1 19.33 2.54 1.95 1R Candidate YSOs 10M,11M 18 29 01.2 01 10 28.0 G9-K3 K1 no 1.1 18.67 2.44 1.76 2R Candidate YSOs 10M 18 29 01.3 01 02 25.0 G5-K5 K0 yes < 1.7 18.99 2.67 2.31 1R Candidate YSOs 10M 18 29 01.4 01 27 06.7 G5-G9 G7 no < 3.0 19.29 1.96 1.16 1R Candidate YSOs 10W,10M,11M 18 29 01.7 01 01 12.2 K2-K4 K3 poss 0.73 18.22 2.62 1.96 3R Candidate YSOs KOB 61 10M 18 29 02.3 01 18 31.0 G9-K3 K0 poss < 2.1 19.46 0.74 1.94 1R Candidate YSOs 10M 18 29 02.3 01 11 53.8 G5-K2 K0 poss < 2.2 19.53 2.35 1.85 1R Candidate YSOs 10M 18 29 02.7 01 03 13.5 K0-K2 K1III no < 1.8 18.59 2.45 1.88 1R Candidate YSOs 10M 18 29 02.9 01 10 00.7 G9-K3 K1 poss 1.1 18.55 2.02 1.33 1R Candidate YSOs 10M 18 29 03.1 01 22 50.8 K0-K3 K1 no 1.0 16.20 2.23 1.43 1R Candidate YSOs 10M 18 29 03.1 01 17 25.2 M3-M4 M3.5 poss -5.5 19.83 1.66 1.42 1R Candidate YSOs 09W,10W,11M 18 29 03.4 01 23 09.8 K2-K3 K2 no 1.1 16.00 2.39 1.42 1B, 3R Candidate YSOs 10M 18 29 04.0 01 06 46.1 G5-K4 K1 no < 1.5 18.98 2.88 1.91 1R Candidate YSOs XMM 06W 18 29 04.5 01 09 47.0
