Beginning of ReadMe : J/A+A/475/559 12CO(1-0) and 12CO(2-1) maps of EP Aqr (Winters+, 2007) ================================================================================ Mass loss from dusty, low outflow-velocity AGB stars. II. The multiple wind of EP Aquarii. Winters J.M., Le Bertre T., Pety J., Neri R. <Astron. Astrophys. 475, 559 (2007)> =2007A&A...475..559W ================================================================================ ADC_Keywords: Stars, variable ; Radio lines Keywords: hydrodynamics - stars: mass-loss - stars: AGB and post-AGB - stars: winds, outflows - radio lines: stars - circumstellar matter 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 ^12^CO(2-1) and ^12^CO(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 ^12^CO(2-1) and ^12^CO(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 0.26x0.26arcsec^2^ for fig6 (^12^CO(1-0)) and 0.14x0.14arcsec^2^ for fig7 (^12^CO(2-1)).
