Table 2:
Line identifications and equivalent widths (EWs; given in Å) for the K band (
2-2.35 
m) spectra of AFGL 2298.
Note that we have adopted the convention that emission lines are quoted as positive throughout the table. We estimate errors of
10 per cent for the UKIRT spectra and 20 per cent for the spectra from Campo Imperatore. Dates are given in month/year form
for brevity; the exact dates of spectra are listed in Sect. 2.2. Note that within the observational uncertainties the EW measured from the 3
low resolution spectra taken between 2002 May-July are identical to one another (hence we only quote a mean value)
while the values obtained from 2001 August (PC02) are identical to those obtained in 2001 June (and are also omitted for brevity).
