MIR band versus optical band magnitudes of eFEDS-DOGs as well as previous X-ray detected DOGs. Red and orange stars denote eFEDS-DOGs and eFEDS-detected DOGs with NHclass < 2, respectively. Blue squares show eFEDS-DOGs with the BluDOG-like feature. Lime, Green, purple, magenta, cyan, and pink plots denote X-ray detected DOGs from Lanzuisi et al. (2009), Corral et al. (2016), Riguccini et al. (2019), Toba et al. (2020), Zou et al. (2020), and Kayal & Singh (2024), respectively. For the sample fainter than m_MIR > 15 mag (e.g., Lanzuisi et al. 2009; Corral et al. 2016; Riguccini et al. 2019), we utilized Spitzer/MIPS 24 μm bands as m_MIR. The optical bands were obtained from the Hubble/ACS F775 band (Corral et al. 2016), Suprime-Cam i_AB′ bands (Riguccini et al. 2019) and heterogeneous optical magnitudes by Vizier with the nearest matching with < 3 arcsec (Lanzuisi et al. 2009). The solid red line represents the DOGs criterion, and three dashed red lines denote (i − W4)_AB = 8.0, 9.0, and 10.0. The numbers in parentheses indicate the number of objects.
