These last ejections are thought to trigger the post-asymptotic giant branch evolution. To assemble an overall picture of how M 2-9 was shaped, we analyzed the characteristics of the different molecular gas components and their relation with the warmer parts of the nebula that are visible in the optical domain. 12CO and 13CO J=3-2 line emission maps were obtained with the Atacama Large Millimeter/submillimeter Array with high angular-resolution and sensitivity. Description: m2-912co3204kms.fits: Cube of channel maps of the 12CO J=3-2 line emission toward M2-9. The center is given by the position of compact continuum emission, here subtracted, at J2000 coordinates RA=17:05:37.966, Dec=-10:08:32.63. The first axis in the cube refers to RA coordinates, second to Declination reference, and third the LSR velocity. The synthesized beam is 0.19x0.16-arcsec with the major axis PA=116-degrees. The spectral spacing of 0.488MHz (0.423km/s). The brightness is presented in Jy/beam units, and the conversion factor into Rayleigh-Jeans-equivalent TMB units is 330K/(Jy/beam). m2-913co3204kms.fits: Cube of channel maps of the 13CO J=3-2 line emission toward M2-9. The center is given by the position of compact continuum emission, here subtracted, at J2000 coordinates RA=17:05:37.966, Dec=-10:08:32.63. The first axis in the cube refers to RA coordinates, second to Declination reference, and third the LSR velocity. The synthesized beam is 0.20x0.17-arcsec with the major axis PA=-79-degrees. The spectral spacing of 0.488MHz (0.442km/s). The brightness is presented in Jy/beam units, and the conversion factor into Rayleigh-Jeans-equivalent TMB units is 326K/(Jy/beam).
