Table 1: Observation log for W243 between 2001-3, giving telescope, instrument, instrumental configuration and resultant wavelength range and dispersion. Note the observations on 8/6/03 were made through clouds. Note for reasons of brevity we have also listed the Equivalent Widths of the H$\alpha $ profiles from each observation; due to the low resolution of the 2001 data (not shown) the error associated with this measurement is substantially higher than subsequent observations.
