12 * @struct AliHLTExternalTrackParam
13 * This in a struct for tracks which are closer to the format used by offline.
14 * The offline parametrisation we find in AliExternalTrackParam class.
15 * The covariance matrix is in Double_t since this is the format in AliExternalTrackParam.
16 * This saves time in translating from Float_t to Double_t. The other values has to be copied
17 * anyway, so these can be Float_t for saveing space.The charge is now removed and the Pt has a sign.
