A catalogue of 541 nearby (within 10pc of the sun) stars, brown
dwarfs, and confirmed exoplanets in 336 systems, as well 21
candidates, compiled from SIMBAD and several other sources. Where
available, astrometry and photometry from Gaia eDR3 has been inserted.
PPMXL is a catalog of positions, proper motions, 2MASS- and optical
photometry of 900 million stars and galaxies, aiming to be complete
down to about V=20 full-sky. It is the result
of a re-reduction of USNO-B1 together with 2MASS to the ICRS as
represented by PPMX. This service additionally provides improved proper
motions computed according to Vickers et al, 2016
(:bibcode:`2016AJ....151...99V`).
Parts I and III of the sixth fundamental catalog, a catalog of
high-precision astrometry for bright stars combining centuries of
ground-based observations as reflected in FK5 with HIPPARCOS
astrometry.
The result contains, in particular for the proper motions,
statistically significant improvements of the Hipparcos data und
represents a system of unprecedented accuracy for these 4150
fundamental stars. The typical mean error in pm is 0.35 mas/year for
878 basic stars, and 0.59 mas/year for the sample of the 3272
additional stars.
The The VO @ ASTRON's sitewide SIAP version 2 service
publishes all the images published through the site. For more advanced
queries including uploads, all this data is also available through
ObsTAP.
The The VO @ ASTRON's TAP end point. The Table Access
Protocol (TAP) lets you execute queries against our database tables,
inspect various metadata, and upload your own data. It is thus the
VO's premier way to access public data holdings.
Tables exposed through this endpoint include: main from the lbcs schema, main, msssvf_img_main from the mvf schema, frb_det, frb_obs from the arts_dr1 schema, img_main, main from the lofartier1 schema, mosaic, source_catalog from the lolss schema, main from the svc schema, img_main, main from the tgssadr schema, main, mom0 from the sauron schema, images, source_catalog from the apertif_dr_bootes schema, columns, groups, key_columns, keys, schemas, tables from the tap_schema schema, hetdex_images, main, main_merged from the hetdex schema, img_main from the msss schema, obscore from the ivoa schema, beam_cubes, calibrated_visibilities, continuum_images, flux_cal_visibilities, pol_cal_visibilities, pol_cubes, raw_visibilities, spectral_cubes from the apertif_dr1 schema, main_gausses, main_sources, mosaics from the lotss_dr2 schema.
The Tohoku University VO Server's TAP end point. The Table Access
Protocol (TAP) lets you execute queries against our database tables,
inspect various metadata, and upload your own data. It is thus the
VO's premier way to access public data holdings.
Tables exposed through this endpoint include: epn_core from the iitatehf schema, columns, groups, key_columns, keys, schemas, tables from the tap_schema schema, epn_core from the iprt schema, epn_core from the irtf_cshell schema, epn_core from the hisaki schema, epn_core from the sw_model schema, emptyobscore, obscore from the ivoa schema.
This service provides oscillator strengths and transition
probabilities. Mainly based on experimental energy levels, these were
calculated with the pseudo-relativistic Hartree-Fock method including
core-polarization corrections.
The UCL DaCHS server's TAP end point. The Table Access
Protocol (TAP) lets you execute queries against our database tables,
inspect various metadata, and upload your own data. It is thus the
VO's premier way to access public data holdings.
Tables exposed through this endpoint include: columns, groups, key_columns, keys, schemas, tables from the tap_schema schema, emptyobscore, obscore from the ivoa schema, epn_core from the mdisc schema.
This table contains the metadata for the plates that went into USNO-B
1.0 as best as we can reconstruct it (i.e., largely those that also
make up the Digital Sky Survey DSS). Most of the source files were
obtained from http://www.nofs.navy.mil/data/fchpix/, some additional
contributions came from Dave Monet.
