IPHAS survey diagram r–Hα vs. r–i for 2630 stars in the area with a diameter of 15′ around the cluster center. The identified A0−A5 and A6–F0 stars are limited by the parabolic interstellar reddening curves. The broken line is the threshold line for T Tauri-type stars from Barentsen et al. (2011). The crosses with numbers are the probable YSOs from Table 2. The errors of magnitudes are ≤0.05 for normal stars and <0.06 for YSOs.
