Orion Spiral Arm CAtalogue (OSACA)
Listed in IVOA Registry (Virtual Observatory)
We transformed radial velocities compiled from more than 1400 published sources, including the Geneva-Copenhagen survey of the solar neighborhood (2004, Nordstrom et al., Cat. <V/117>), into a uniform system based on the radial velocities of 854 standard stars in our list (Gontcharov, 2006, Cat. <III/252> ).
Description
This enabled us to calculate the average weighted radial velocities for more than 25000 HIPPARCOS stars located in the local Galactic spiral arm (Orion arm) with a median error of 1km/s.
We use these radial velocities together with the stars coordinates, parallaxes, and proper motions to determine their Galactic coordinates and space velocities. These quantities, along with other parameters of the stars, are available from the continuously updated Orion Spiral Arm CAtalogue (OSACA) and the associated database. We perform a kinematic analysis of the stars by applying an Ogorodnikov-Milne model to the OSACA data.

The kinematics of the nearest single and multiple main-sequence stars differ substantially.
