VizieR Online Data Catalog: CO observations towards W44E and W44F with APEX (Anderl+, 2014)
Abstract
Observations in 12CO (3-2), (4-3), (6-5), (7-6) towar supernova remnant's region W44E were conducted in July 2010, while observations towards the region W44F were conducted in several runs in the year 2009 (in June and August). We made use of a great part of the suite of heterodyne receivers available for this facility: FLASH345, FLASH460, and CHAMP+, in combination with the MPIfR Fast Fourier Transform Spectrometer backend (FFTS), or with the newly commissioned MPIfR X-Fast Fourier Transform Spectrometer backends (XFFT). Focus was checked at the beginning of each observing session, after sunrise and/or sunset on Mars, Jupiter, or Saturn. Continuum and CO line pointing was locally established on G34.26 and R-Aql. The pointing accuracy was found to be of the order of 5" r.m.s, regardless of the receiver that was used. The observations were performed in position-switching/raster mode using the APECS software. The data were reduced with the CLASS software. Here we provide the velocity integrated maps of 12CO (3-2), (4-3), (6-5), and (7-6) for the blue wing (20-40km/s), red wing (50-70km/s), and ambient (40-50km/s) emission. The CO (7-6) map was smoothed to the resolution of CO (4-3) in order to improve the signal-to-noise.
