Notes. Column 2 provides the spectral type, while Columns 3 and 4 show the V−and K−magnitudes, respectively, as obtained from the SIMBAD7 Astronomical Database. Column 5 contains the parallax values along with their associated errors, sourced from the Gaia Data Release 3. Column 6 reports ΔV, which represents the amplitude variation of the V−magnitude, collected from the AAVSO8 database. In the seventh column we present the variability type of our sample stars based on the light curves from the KWS survey (Maehara 2014), where ‘SRV’ stands for semi-regular variable and ‘Mira’ for Mira-type variables. In the last column we enlist the height above the Galactic plane |Z|. aGaia data release 2 parallax
