1 Mendez, Manuel J. V magnitudes transformed from Gaia DR3 have been used for the reference stars Gaia DR3 4265353737022825984 (V= 13.86) and Gaia DR3 4265350786465453696 (V= 13.92). ASAS-SN V magnitudes contaminated by Gaia DR3 265350786382699264 (V= 16.8; sep. 9"), Gaia DR3 4265350786465470976 (V= 16.5; sep. 9") and other fainter nearby stars. Range has been corrected. Primary eclipse might be the secondary.
