-**Note:** When num_y_points is equal to 0, this process may use uninitialized values within ar_coeffs_y_plus_128 to compute LumaGrain.
+**Note:** When num_y_points is equal to 0, this process may use uninitialized values within ArCoeffsYPlus128 to compute LumaGrain.
 However, LumaGrain will never be read in this case so it does not matter what values are constucted.
 Similarly, when num_cr_points/num_cb_points are equal to 0 and chroma_scaling_from_luma_flag is equal to 0, the CbGrain/CrGrain arrays will never be read.
