Abstract:
  Using high-resolution spectra obtained with the Hamilton echelle
  spectrograph at Lick Observatory, we have constructed a catalog of
  emission lines observed in comets Swift-Tuttle and Brorsen-Metcalf.
  The spectra cover the range between 3800 A and 9900 A with a spectral
  resolution of Lambda/Delta(Lambda) ~ 42000.  In the spectra, we catalog
  2997 emission lines of which we identify 2438.  We find cometary lines
  due to H, O, C2, CN, NH2, C3, H2O+, CH, and CH+.  We list 559
  unidentified lines compiled from the two spectra and comment on
  possibilities for their origins.

Notes for file: table1.dat
--------------------------------------------------------------------------------
n_L_CT, n_L_BM:
  A "+" in this column indicates that the line with the wavelength
  listed in the previous row has been identified as a blend of two or
  more lines, with the laboratory wavelengths and identifications
  given in the subsequent rows.

I_CT, I_BM:
  These intensities are corrected for the echelle blaze function, but
  not for CCD response or atmospheric absorption.  The relative
  intensities are thus reliable within a spectral order but not
  between widely spaced orders.
