Query: Intrinsic properties of a complete sample of HETE-2 gamma-ray bursts. A
  measure of the GRB rate in the Local Universe   Aims: Taking advantage of the forthcoming Catalog of the HETE-2 mission, the
aim of this paper is to evaluate the main properties of HETE-2 GRBs - the
E_peak, the T_90 and the E_iso - in their source frames and to derive their
unbiased distribution. Methods: We first construct a complete sample containing
all the bursts localized by the WXM on-board HETE-2, which are selected with a
uniform criterion and whose observed parameters can be constrained. We then
derive the intrinsic E_peak, T_90 and E_iso distributions using their redshift
when it is available, or their pseudo-redshift otherwise. We finally compute
the number of GRB (N_Vmax) within the visibility volume (V_max) of each GRB, in
order to derive a weight for each detected burst accounting both for the
detection significance and the star formation history of the universe. Results:
The unbiased distributions obtained clearly show the predominence of X-ray
flashes (XRFs) in the global GRB population. We also derive the rate of local
GRBs: R0^H2 > 11 Gpc-3 yr-1, which is intermediate between the local rate
obtained by considering only the high-luminosity bursts (~1 Gpc-3 yr-1) and
that obtained by including the low-luminosity bursts (>200 Gpc-3 yr-1).
