Title: All-sky search for periodic gravitational waves in LIGO S4 data

LIGO Scientific Collaboration: B. Abbott, et al

Comments: 39 pages, 41 figures An error was found in the computation of the C parameter defined in equation 44 which led to its overestimate by 2^(1/4). The correct values for the multi-interferometer, H1 and L1 analyses are 9.2, 9.7, and 9.3, respectively. Figure 32 has been updated accordingly. None of the upper limits presented in the paper were affected
