Description of the content of the PM catalogues

Column Name Unit Description
1 RA [deg] Right ascension (ICRS) at epoch 2016.0
2 Dec [deg] Declination (ICRS) at epoch 2016.0
3 X [pixel] X position on the master frame;
pixel scale of 40 mas pixel−1 and the cluster centre at ∼(10 000, 10 000)
4 Y [pixel] Y position on the master frame;
pixel scale of 40 mas pixel−1 and the cluster centre at ∼(10 000, 10 000)
5 (μα cosδ)corr [mas yr−1] Corrected PM along RA direction
6 (σμα cosδ)corr [mas yr−1] Error of corrected PM along RA direction
7 (μδ)corr [mas yr−1] Corrected PM along Dec direction
8 (σμδ)corr [mas yr−1] Error of corrected PM along Dec direction
9 χ μ α c o s δ 2 $ \chi^2_{\mu_{\alpha}\,\mathrm{cos}\delta} $ Reduced χ2 of the PM fit along RA direction
10 χ μ δ 2 $ \chi^2_{\mu_{\delta}} $ Reduced χ2 of the PM fit along Dec direction
11 Nf Initial number of exposures available for PM fit
12 Nu Final number of exposures actually used for PM fit

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
