This services provides 1D spectra from DR5 of LAMOST (Large Sky Area Multi-Object Fiber Spectroscopic Telescope) through SSAP; data is served both in VO-standard SDM and, via... -
UCAC3 nocross
The UCAC3 all-sky CCD astrograph catalogue, minus the fields from 2MASS and SuperCosmos and matching/object flags (which can be recovered with a local crossmatch). -
Corrections between UCAC3 and PPMXL
Differences between UCAC3 and PPMXL in positions and proper motions, on an all-sky one-degree grid. At each gridpoint we give the differences X(PPMXL)- X(UCAC3) averaged over... -

Joined Bayestar17 3D Dust Map
This is a view of the dust maps in the five orders, generated by splitting the larger pixels from the higher orders into HEALPixes of order 10. This means, in particular, that... -
Scans of the Palomar-Leiden Trojan Survey Plates
This service publishes plate scans of the Palomar-Leiden Troian surveys conducted between 1960 and 1977. The surveys led to the discovery of more than 2,000 asteroids (1,800... -
