... Contents of the Tycho Catalogue Over view of the Tycho Catalogue: The Tycho Catalogue provides astrometr y (positions, parallaxes and proper motions) and two-colour photometr y (in B T and VT ) for more than one million stars brighter than VT = 11.5 mag. ... Stars in ver y dense clusters and other dense fields thus leaving the resulting Tycho Catalogue incomplete in such regions `R' in Field T42). ... The number of non-Hipparcos stars with Tycho Catalogue parallaxes larger than 40 + 4 mas is 1245. ...
... X-ray data of GX 3+1 (4U 1744-26) obtained in broad energy ranges using BeppoSAX (0.1200 keV) and Rossi X-Ray Timing Explorer (RXTE) (3200 keV) offer a unique The Astrophysical Journal, 747:99 (15pp), 2012 March 10 Seifina & Titarchuk possibility to further investigate, in detail, the evolution of X-ray spectral properties during transition events. ... In Figure 2, we illustrate our spectral model as a basic model for fitting the BeppoSAX and RXTE spectral data for GX 3+1. ... Figure 4. ...
