J/A+A/385/1014      Magnetic field structure in W51A       (Chrysostomou+, 2002)

The magnetic field structure in W51A Chrysostomou, A., Aitken, D.K., Jenness, T., Davis, C.J., Hough, J.H., Curran, R., Tamura, M. <Astron. Astrophys. 385, 1014 (2002)> =2002A&A...385.1014C
ADC_Keywords: Interstellar medium ; Polarization ; Magnetic fields ; Radio lines Keywords: ISM: magnetic fields - ISM: individual objects: W51A - stars: formation - techniques: polarimetric - submillimetre Description: We present 850µm imaging polarimetry of the W51A massive star forming region performed with SCUBA on the James Clerk Maxwell Telescope (JCMT) situated close to the summit of Mauna Kea, Hawaii, on the night 6 October 2000. Positions, fluxes and polarimetry of the data points shown in Fig. 1 of the paper are reported in the file table2.dat. The positional offsets are given relative to W51d (19:23:39.0, +14:31:08, J2000). All fluxes (including the Stokes Q and U parameters) are given in units of Jy/beam. The position angles give the direction of the E-vector. File Summary:
