| Abstract: | We present here an extensive list of internally consistent oscillator strengths for Fe I lines. We have compiled and critically reviewed the oscillator strengths existing in literature. An attempt has been made to scale the oscillator strengths derived by different workers to that of Blackwell and his collaborators and prepare a single consistent set of oscillator strengths. We have calibrated a loggf- log λ- E 1- log I relationship that can be used for calculatinggf values for Fe I lines with nogf values available. We demonstrate that standard error of such a calibration can be considerably reduced by binning the data in 0.5 eV range in excitation potential. We also tabulate systematic corrections to be applied to the oscillator strengths of Kurucz & Peytremann (1975) for lines belonging to different multiplets |
