Those are the parameters for a World file that allow the correct placement of raster images.
0.00852919145063922, // How much longitude each X pixel represents
0.000000, // Rotation about Y-axis
0.000000, // Rotation about X-axis
-0.00852919145063922, // How much latitude each Y pixel represents
-117.210491069447, // Longitude of the upper left pixel (West point)
34.8362619850852 // Latitude of the upper left pixel (North point)
