Information on Service 'The Fifth Catalogue of Nearby Stars (CNS5)'

Further access options are discussed below

The Fifth Catalogue of Nearby Stars (CNS5) aims to provide the most volume-complete sample of stars in the solar neighbourhood. The CNS5 is compiled based on trigonometric parallaxes from Gaia EDR3 and Hipparcos, and supplemented with astrometric data from Spitzer and ground-based surveys carried out in the infrared. The CNS5 catalogue is statistically complete down to 19.7 mag in G-band and 11.8 mag in W1-band absolute magnitudes, corresponding to a spectral type of L8. Continuous updates of observational data for nearby stars from all sources were collected and evaluated. For all known stars in the 25 pc sphere around the Sun, the best values of positions in space, velocities, and magnitudes in different filters are presented.

Overview

You can access this service using:

form -- an interface for web browsers through an HTML form
scs.xml -- a standard SCS interface as defined by the IVOA to access catalog-type data; SCS clients use http://dc.zah.uni-heidelberg.de/cns5/q/cone/scs.xml? to access the service

This service is published as follows:

Within the set(s) ivo_managed with the renderer dali
Within the set(s) ivo_managed,local with the renderer form
Within the set(s) ivo_managed with the renderer scs.xml

local means it is listed on our front page, ivo_managed means it has a record in the VO registry.
