Abstract	All-sky searches for continuous gravitational waves require a very high computational cost. For this reason it is more convenient to perform a hierarchical search rather than a coherent one. The Frequency-Hough pipeline uses a tool -known as Hough transform- to achieve this goal. Anyway, the number of candidates typically returned by such pipeline is quite high (O(10^12)). To solve this problem we have deeply studied the patterns that these candidates produce in the search parameter space (given by the source frequency, frequency derivatives and sky position) as a consequence of the Earth Doppler modulation. This has resulted into a chain of novel veto algorithms, which is useful to streamline candidates not consistent with a continuous-wave signal.
