Notes. Column 1: shortened SDSS object name. Column 2: Chandra observation identification number. Column 3: Chandra observation date (UT). Column 4: Chandra net exposure after cleaning in seconds. Column 5: Chandra 0.5−7.0 keV net counts derived from a 2′′ radius aperture. For detected sources, we quote Poisson errors derived from Gehrels (1986) at 1σ confidence level. For undetected sources, we derive 99% confidence upper limits based on the Bayesian technique of Kraft et al. (1991). Column 6: galactic Hi column density from Kalberla et al. (2005) in 1020 cm-2. Column 7: observed 2−10 keV luminosity or limit assuming a Γ = 1.8 powerlaw spectrum absorbed by Galactic NH, in erg s-1. Column 8: expected 2−10 keV luminosity based on the LX–LHα relation of P06, in erg s-1.
