Abstract:
    CO rotational lines are frequently used to trace the outflows from
    AGB stars. Some profiles are composite, with a narrow component
    super-imposed on a broader one. These profiles have been interpreted
    in different ways, calling for episodic mass loss, a bipolar flow, or
    a circumstellar disk.

Description:
    We have obtained detailed 12CO(2-1) and 12CO(1-0) spectral maps of
    EP Aqr, a prototypical source with composite CO profiles.
    Interferometric data were acquired with the IRAM interferometer and
    combined with on-the-fly maps obtained at the IRAM 30-m. The resulting
    maps in 12CO(2-1) and 12CO(1-0) cover a field of 100"x100" with a
    spectral resolution of 0.1km/s and with synthesized beams of
    1.7"x1.0" and 3.5"x1.8", respectively. The FITS files presented here
    contain the spectral data cubes, rebinned to a velocity resolution of
    1km/s. Each of the 26 velocity channels contains a map of 256x256
    pixels of size 0.26x0.26arcsec2 for fig6 (12CO(1-0)) and
    0.14x0.14arcsec2 for fig7 (12CO(2-1)).
