AFGL 2591 Archives

AFGL 2591 integrated intensity R TAdv (K km s−1 ) maps of rotational transition lines spanning a range of energy levels. The upper state energy level is indicated in the top right-hand corner and the beam size in the bottom left-hand corner. The source VLA 3 is noted by a white or black ‘x’. CH3CCH, in the first column, c-C3H2, in the second, H2CO, in the third, have contour levels of 10, 20, 30, and 40 times the noise level of the respective frequency range. CH3OH, in the fourth column, has contour levels of 10, 20, 40, 80, and 120 times the noise level of the respective frequency range. -- astro-ph.SR
