Description:
   These data characterize the extended low-density warm ionized medium
   (the ELDWIM). The file contains results from a Radio Recombination Line
   survey of the inner Galaxy at 583; emission was observed at 418 points.

Note on n_Tb:
   GB  = observation was made at NRAO
   HC  = observation was made at HCRO
   Sxx = position is close to Sharpless HII region xx
   ic  = spectrum has i Gaussian components
   W   = detection is weak
   note 1 = Spectra plotted and discussed in HKLR (Heiles et al. 1995)
   note 2 = This spectrum (l,b) = (31.50, -3.00) has an extraordinarily
      wide Gaussian. It may be more appropriately fitted by two Gaussian
      with (Tb, FMHM, Vlsr) = (6.3, 53.5, 44.2) and (6.6, 36.2, 105.0)
      but the signal/noise does not warrant these extra parameters.
