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.
