A T N F @ A S C observations in the project


Project’s flow chart: observations in the project Stage I – selection of the ROSAT hard spectrum sources [VO]. Stage II – tentative radio IDs [VO].Stage III –high resolution radio observations.Stage IV – optical IDs [VO]; . galaxies to be discarded.Stage V – optical spectroscopy.

A T N F @ A S C


Stage I observations in the project – selection in X-ray from theBright ROSAT Sources Catalogue (1RXS) [W. Voges et al., A&A 349, 389, 1999]

The main selection criterium =

= Motch’s Strip :

0.90 ≤ HR1 ≤ 1.00

0.25 ≤ HR2 ≤ 1.00

[ C. Motch et al., A&A 132, 341, 1998 ]

AND Sources in the Galactic Plane:

|b| < 200

Stage ii tentative identifications in radio surveys
Stage II observations in the project – tentative identifications in Radio Surveys:

  • NVSS (VLA, D-configuration) 1.4 GHz

  • 87GB/GB6/PMN (single dish) 4.8 GHz

    -----&----

    radio variability

    checking

    [GB6] = { [1987GB]2 + [1989GB]2} -2

Stage ii
Stage II: observations in the project

The X-ray-Radio cross-identifications

have been made usingCATS:

a major collection of databases gathered and maintained by

S. Trushkin et al. of the Special Astrophysical Observatory

Stage iii targeted radio observations with a sub arcsec coordinate precision
Stage III: observations in the project Targeted radio observations(with a sub-arcsec coordinate precision):

  • VLA

    A-configuration, 1.4 & 4.8 GHz

  • ATCA

    6-km configuration, 4.8 & 8.6 GHz

Stage IV: observations in the project Radio-Optical Identifications by the Digital Sky Surveys (DSS)[obvious galaxies were discarded]

A Virtual Observatory observations in the project of theUS Naval Observatory,Flagstaff Station, Arizona:USNO PMMhttp://www.nofs.navy.mil/projects/pmm/Observables: coordinates; charts; images;B, R, I magnitudes at two epochs, (hence variability); image analysis (star/galaxy); proper motions (!)of ~1,000,000,000objects,release B1.0, 2003.


USNO PMM: observations in the project ►flexible multiparameter interface;► multidata output.The best, but not perfect: no multisource query.
