Erratum
Erratum to ‘‘Energy flow in a hadronic cascade: Application to hadron calorimetry’’ [Nucl. Instr. and Meth. A 572 (2007) 633– 653] Donald E. Groom Lawrence Berkeley National Laboratory, 50R6008, Berkeley, CA 94720, USA
Four errors have been found in the paper, the first of which is serious:
1. In Fig. 13 the labels ‘‘Intrinsic em’’ and ‘‘Intrinsic had’’ were reversed. The difference in curvatures is essential to understanding Eq. (15). 2. In Table 3 there was an error in the upper right entry, which should be 372% rather than 318%, and 3. an error in footnote (a), which should read: a
sp0 ¼ s1 ðE=100 GeVÞs2 .
4. There was a sign error in footnote 4 on p. 635, which should read: 4
A slightly better fit is obtained with 0:126 0:0099 lnðE=100 GeVÞ.
