CHASFRXRAY - ROSAT All-Sky Survey: Chamaeleon Star Forming Region Study
The RXJ X-ray source designation.
The Right Ascension of the X-ray source.
The Declination of the X-ray source.
The galactic longitude of the X-ray source.
The galactic latitude of the X-ray source.
The ROSAT PSPC count rate in cts/s.
The RMS uncertainty in the count rate, in cts/s.
The proposed optical identification for the X-ray source.
The offset between the positions of the X-ray source and the proposed optical counterpart, in arcseconds.
The spectral type of the (stellar) optical counterpart.
A code describing the type of the optical counterpart in those cases when it could be identified with no ambiguity:
W : previously known weak-line T Tauri star C : previously known classical T Tauri star Wn : new weak-line T Tauri star UAS: unrelated active star UBS: unrelated bright star IR : infrared source QS : quasar RS : radio source G : galaxy
A note describing the appearance of the optical counterpart in the finding chart:
ST.: Stellar GAL.: galaxy FAINT: object fainter than V~20. A : source investigated spectroscopically, but without stellar counterpart found. B : source not investigated. Its corresponding error circle contains objects fainter than our limit for the spectroscopic observations (V~17mag). C : very strong spectroscopic and photometric variability (Alcala et al. 1993A&A...272..225A). D : H-alpha filled-in with emission but no Li I 6707A absorption. E : Li I 6707A absorption to be confirmed because of low S/N of the spectrum.
