Interoperability tools for the Virtual Observatory

open access: yes, 2001
Interoperability is one of the key issues in the current efforts to build the Virtual Observatory. We present here some of the tools which already contribute to the efficient exchange of information between archives, databases, and journals.

The XinJiang Astronomical Observatory NSRT Pulsar Data Archive

open access: yesAdvances in Astronomy, 2019
The sensitivity of our pulsar observation system with typical integration time of 16 minutes has reached 0.4 mJy after we have upgraded the receiver cooling system of NanShan 25-m radio telescope (NSRT) at Xinjiang Astronomical Observatory (XAO) in 2002.

The operation of VEGA/CHARA : from the scientific idea to the final products [PDF]

open access: yes, 2013
We describe the data flow in the operation of the VEGA/CHARA instrument. After a brief summary of the main characteristics and scientific objectives of the VEGA instrument, we explain the standard procedure from the scientific idea up to the execution of

SearchCal: a virtual observatory tool for searching calibrators in optical long baseline interferometry [PDF]

open access: yesAstronomy & Astrophysics, 2006
In long baseline interferometry, the raw fringe contrast must be calibrated to obtain the true visibility and then those observables that can be interpreted in terms of astrophysical parameters. The selection of suitable calibration stars is crucial for obtaining the ultimate precision of interferometric instruments like the VLTI.
