- Description:
- The RAdial Velocity Experiment (RAVE) contains stellar atmospheric parameters (effective temperature, surface gravity, overall metallicity), radial velocities, chemical abundances and distances. Observations between 2003 and 2013 were used to build the five RAVE data releases.

- Description:
- The pulsar timing data were obtained with the Nanshan 25M radio telescope. Our observations, which commenced in January 2000, have been made using a dual-channel room-temperature receiver with a bandwidth of 320 MHz centered at 1540 MHz before June 2002. The de-dispersion was provided by a 2X128X2.5 MHz analog filter-bank. A cryogenic receiver was mounted in July 2002, which increases the sensitivity to 0.5 mJy. In January 2010, a digital filter-bank (DFB) system came into operation. The higher time resolution allows us to monitor about 280 pulsars, including ten millisecond-pulsars (MSP). The format of the DFB data is "Psrfit". The "psrchive" program could reads and analyzes the data. Timing observations of 74 pulsars have been regularly carried out between 2002 July to 2009 December. These 74 pulsars have been monitored approximately once every 9d using a dual-channel cryogenic system that receives orthogonal linear polarizations at the central observing frequency of 1540 MHz. The folded profiles obtained are released in format PSRFITS for timing analysis, the file name extension is .FTp. Users can enter "~*.FTp*" in "Product key" filed to search and download it. Non-public data could be used with the permission of Dr. Shengnan Sun (sunshengnan@xao.ac.cn), please send an email for your request.

- Description:
- The LIFE Target Star Database contains information useful for the planned `LIFE mission`_ (mid-ir, nulling interferometer in space). It characterizes possible target systems including information about stellar, planetary and disk properties. The data itself is mainly a collection from different other catalogs. Note that LIFE's target database is living data. The content – and to some extent even structure – of these tables may change at any time without prior warning. .. _LIFE mission: https://life-space-mission.com/

- Description:
- ARI's "Geschichte des Fixsternhimmels" is an attempt to collect all astrometrically useful observations from before ca. 1970 in a way comparable to what has been done to construct the FK* series of fundamental catalogs. About 7e6 published positions are included. In GAVO's DC, we provide tables of identified and non-identified stars together with the master catalog that objects were identified against.

- Publisher:
- The GAVO DC team
- Description:
- This is a clean and well characterised catalogue of objects within 100pc of the Sun from the Gaia early third data release. We characterise the catalogue using the full data release, and comparisons to other catalogues in literature and simulations. For all candidates (measured parallax < 8 mas), we calculate a distance probability function using Bayesian procedures and mock catalogues for the prediction of the priors. For each entry using a random forest classifier we attempt to remove sources with spurious astrometric solutions. This results in 331312 objects that should contain at least 92% of stars within 100 pc at spectral type M9. GCNS comes with several auxiliary tables, in particular lists of resolved stellar systems, of known neary stars not found in eDR3 and of candidates of Hyades and ComaBer cluster members.

- Description:
- Active Galactic Nuclei (AGNs) are extragalactic objects characterized by extremely complex physical processes and strong temporal flux variability over almost the whole electromagnetic spectrum, which play a very important role in studying the formation and evolution of galaxies, cosmology and many other astrophysical problems. Flux variability is one of the most remarkable observational characteristics of AGNs and the variability time scales are from minutes to dozens of years. Multi-wavelength flux monitoring is the main means to study the nature of AGN flux variability. In order to systematically study the total flux variability of AGNs in radio band, we launched a long-term program, which is called the quasi- Simultaneous Multiwavelength Monitoring of AGNs with the Nanshan 26-m radio telescope of Xinjiang Astronomical Observatory (XAO), namely SMMAN program. The monitoring data were acquired monthly with the cross-scan mode at C-band (4.8 GHz) and K-band (23.6 GHz) for a sample of about 100 AGNs selected from Fermi-LAT suvery. Additionally, we also conducted weekly monitoring observations or Intra-Day Vairibility (IDV) observations for some of flaring Blazars to reveal their more complex variability time scales.
