Abstract:
   The equivalent widths of total 546 lines (26 elements are included) in
   the spectrum of the bright Am star Sirius from 380 to 930 nm are tabulated.
   The high-resolution, high signal-to-noise ratio spectrum was obtained 
   with the Coude Echelle Spectrograph attached to the 2.16 m telescope at 
   Beijing Astronomical Observatory (Xinglong, China). Here we also give the 
   results of the equivalent widths comparison between our measurements and 
   those of Strom et al. (=1966ApJ...146..880S) and Sadakane & Ueta 
   (=1989PASJ...41..279S).

Note on Qual:
  The flags only give readers a rough estimation of line quality.  Different 
  people may adopt a slightly different opinion for the choice of flag number.
  The flag numbers 1-3 are recommended to be used in accurate abundance 
  determinations.
