Abstract
Hipparcos data will provide the first unbiased probe of the phase space distribution of stars within 150 pc almost devoid of systematic errors. This probe will be used to trace small scale inhomogeneities of the gravitational potential which may play a role in the unexplained mechanism of the stellar disc heating. The phase space distribution of an homogeneous sample of tracer stars will be analysed in the Orthonormal Wavelet Representation. We present the method used and its calibration in terms on limits of detection in size, signal to noise ratio of the inhomogeneities on 2D simulations.
