Use of matrix direct methods for low-resolution phase extension for tRNA. Erratum

In Podjarny & Yonath [Acta Cryst. (1977). A33, 655-661] the matrix order in Table 1 and point T5(MODF) of Fig. 2 should read 100 instead of 226. The matrix order in points T3(MIR) and T3(MODF) of Fig. 2 should read 450 instead of 226. The MW value of predicted and MIR phases correlation in the whole 3 Å sphere in Table 1 should read 0.2 and not 0.85. Figs. 6(c) and 6(d) should be interchanged.
