The authors use the observed equivalent widths of 50 Co I lines and cobalt abundance lg A = 4.98 to derive the oscillator strengths (gf) of these lines. In addition, for 14 lines from the total list the oscillator strengths (gfHFS) were obtained with accounting for their hyperfine structure. Clear dependences of the difference lg gf - lg gfHFS on equivalent width and excitation potential are revealed. Using these dependences, the authors have corrected all the oscillator strengths obtained without accounting for the hyperfine structure.
