Apparent positions of pulsating AGB stars in equatorial coordinates. Left panel: all known C stars that are periodic and have |Z| > 5 kpc. The sinusoid is an eye fit to the majority of these C stars. Middle panel: stars of our sample (M type) having |Z| > 5 kpc. Right panel: stars of our sample having |Z| < 5 kpc. Dashed lines indicate |b| = 20°. We note that M stars are more numerous than C stars along the Sgr arms.
