IRAM 30m CO-observations in W43 (Carlhoff+, 2013)

Abstract : We observed molecular clouds in the giant star forming region W43. For this project we used the IRAM 30m telescope to observe the molecular emission lines 13CO (2-1) and C18O (2-1), that trace the mid-density (n~103cm-3) molecular gas. The lines were observed with the HERA receiver and the VESPA backend. At the observed frequencies the IRAM 30m has a beam size of 11.7". We include two FITS files containing the data-cubes (pos-pos-vel) of the 13CO and C18O emission lines of the W43 complex. We used equatorial coordinates for the spatial dimensions and vlsr for the spectral dimension. The pixel size is 5.9" in spatial dimension and the spectral resolution is 0.16km/s. All values are in K. The data-cubes span an area of about 1x1.5° (RAxDec) around the center of the maps at 18:46:54.4 -02:14:11 (EQ=J2000) and the velocity range from 30 to 130km/s and include the complete W43 complex and several fore- and background clouds. (2 data files).
