PPM Analysis

The PPM catalog was extracted using XCATSCAN and divided up into 2mass scan-like strips 8 degrees long (the shortest scan in the current survey strategy) and 8 wide. As of now, only the northern hemisphere has been used, which was picked because the northern hemisphere is the lowest density, most non-uniform part of the PPM). The results for the number of scans in the Northern Hemisphere with a given number of PPM stars:
