Notes. Right ascension (RA) and declination (Dec) coordinates as derived from the VIMOS astrometric calibration. Top and bottom panels list the 11 photometric USco candidates from the combined VIMOS–UKIDSS Survey (Sect. 3.1). The top panel indicates candidates that were also found in the VIMOS-only search (Sect. 3.2).

(a)

USco member discovered and confirmed by Lodieu et al. (2006, 2008). It has W3 = 11.034 ± 0.136 mag.

(b)

High proper motion source (Sect. 3.5) discovered by Deacon et al. (2009).

(c)

Candidate with spectroscopic follow-up (Sect. 4).

(d)

Non-photometric candidate according to the diagrams of Fig. 5.

(e)

We provided J-band PSF photometry. ZYHK photometry as in the UKIDSS catalog (we checked that the PSF photometry of these bands agrees with UKIDSS aperture photometry within the quoted error bars).

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.
