5433 events are shown (924 events >100o zenith) from the 2006 dataset.
The likelihood ratio is evaluated on a 0.25ox0.25o grid ranging from -5o<δ<82.5o. At each point the significance is calculated, resulting in the following map:
The maximum significance obtained is 3.58σ near 12.18h, +58.5o. Out of 100 sets of randomized data, 84 have a maximum significance equal to or greater than 3.58σ. The map from 2005 is shown below for comparison (in different units of log10(p-value); however, the hot spots can still be compared easily):

The method is applied to the locations of potential sources in the IC-9 point source catalog and the obtained limits (E2Φ < μ90*10-11 TeV cm-2s-1) and p-values (probability the result is due to background alone) are summarized in the table below.| Object | RAo | Zenitho | P-value | μ90 |
