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 3800A and 9900A with a spectral
resolution of λ/{DELTA}λ∼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.

1- 7 F7.2 0.1nm LamST []? Wavelength for line from Swift-Tuttle
8 A1 --- n_LamST *[+] Flag for blend with previous line
10- 13 I4 --- IntST *[]? Relative intensity of Swift-Tuttle line
17- 23 F7.2 0.1nm LamBM []? Wavelength, line from Brorsen-Metcalf
24 A1 --- n_LamBM *[+] Flag for blend with previous line
26- 29 I4 --- IntBM *[]? Rel. intensity of Brorsen-Metcalf line
33- 39 F7.2 0.1nm LamLab []? Laboratory wavelength of identified line
43- 48 A6 --- Species Identified molecule or 'unid.'
51- 66 A16 --- Band Identified band or blank
70-110 A41 --- Trans Identified transition, or blank
--------------------------------------------------------------------------------
Note on n_LamST, n_LamBM:
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.
Note on IntST, IntBM:
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.
