We present a new abundance analysis of HE 1327 - 2326 , the currently most iron-poor star , based on observational data obtained with VLT/UVES . We correct the 1D LTE abundances for 3D effects to provide an abundance pattern that supersedes previous works , and should be used to observationally test current models of the chemical yields of the first-generation SNe . Apart from confirming the 1D LTE abundances found in previous studies before accounting for 3D effects , we make use of a novel technique to apply the 3D - 1D corrections for CNO which are a function of excitation potential and line strength for the molecular lines that comprise the observable CH , NH , and OH features . We find that the fit to the NH band at 3360 Å is greatly improved due to the application of the 3D - 1D corrections . This may indicate that 3D effects are actually observable in this star . We also report the first detection of several weak Ni lines . The cosmologically important element Li is still not detected ; the new Li upper limit is extremely low , A ( { Li } ) < 0.62 , and in stark contrast with results not only from WMAP but also from other metal-poor stars . We also discuss how the new corrected abundance pattern of HE 1327 - 2326 is being reproduced by individual and integrated yields of SNe .
