Fields explanation

1. NAME

   In the case of HD, HIP and GJ-Gl names, you must write the number of the star. If the star is called by other name (actually variable name), you can write it in the field 'OTHER NAME'. It is not needed capital letters, but you must respect spaces.
   
   

2. Radial Velocity

   Radial velocities are compilated from the latest values given in the literature, and some of then have been meassured by us.
   
   

3. Proper Motion

   We have used proper motion given by the TYCHO-2 Catalogue and Hipparcos Catalogue. Several of the stars have not been observed by Hipparcos and we have obtain their proper motion from Positions and Proper Motions - North
   
   

4. Space Motion

   Galactic Velocity messured in a right-handed reference system, with W pointing towards the north galactic pole, U towards the galactic center and V in the direction of rotation.
   
   

5. Eggen Criteria

   Main criteria for study moving groups given by Olin Eggen are Peculiar Velocity and Radial Velocity. Both of them are given in the results for moving groups with known convergent point (Local Association, Hyades , Ursa Major and IC 2391).
