1 Peretto, Ivo Unresolved companion with V= 12.0 contaminating the mira magnitudes. Gaia DR3 data show a lower limit for the amplitude of 2.0 in G (starting to resolve the pair). Color behaviour (larger amplitudes in redder wavelengths) in ASAS-SN, ZTF, APASS and Gaia DR3 data confirm the presence of the companion. According to APASS, it is rather red too, since near the mira minimum it shows V= 11.98 and B-V= 1.50. Range in the table has been corrected. Light curves are for the blend.
2 Nicholson, Martin B-V = 1.23; J-K = 1.676
