VizieR Online Data Catalog: Western Magellanic Bridge HI observations (Muller+, 2003)
Abstract
Here we present high spatial and velocity resolution observations of the Magellanic Bridge, conducted with both the Australia Telescope Compact Array (ATCA) and with the Parkes telescope.
ATCA observation of the 21-cm H I line were made over a 7x6deg2 field using the 375-m configuration of the ATCA. These observations were made over three sessions: 1997 April 13, 15-16, 18; 1997 October 9-15; and 2000 January 29-February 2. The ATCA observations were made using a 4-MHz bandwidth, with 1024 channels at a central frequency of 1.420GHz. Parkes observations were made using the Multibeam receiver on the 64-m Parkes telescope, during 1999 November 2-8. Only the seven inner receivers of the Multibeam array were used, with each beam having a FWHM width of 14.1arcmin. 48 overlapping scans were made in declination, using the on-the-fly mapping mode at 1deg/min in declination. The scans were centred on RA=02h00m, DE=-72{deg}20', and extended 8{deg} in declination and in RA, large enough to fully encompass the area observed with the ATCA. (1 data file).- Publication:
