In the analysis for our paper on D* production, the beauty contribution was erroneously
subtracted twice in the extraction of the reduced cross sections. This affected
tables 9 and 10 as well as figures 9 and 10 that are reproduced here in a corrected version.
The kinematical acceptances shown in the last colum of table 10 have been also corrected
since they were calculated with a different value for the charm fragmentation fraction than
what was used in the rest of the analysis and reported in the text. A misprint was found
in table 7: the value in the third column at four rows from the bottom should read 49.8,
not 59.8. Finally, one of the authors was missing from the author list: C. Uribe-Estrada
(Department of Physics, University of Oxford, United Kingdom).
