Notes. Significance levels above 99% confidence, according to the F-test in (a) and according to Monte Carlo simulations in (b), are reported in boldface. Column 1: ObsID and image; Col. 2: line energy (in units of keV); Col. 3: line rest-frame equivalent width (in units of eV); Col. 4: blind-search confidence level; Col. 5: F-test confidence level; Col. 6: Monte-Carlo-simulation confidence level. All the errors are computed at a 90% confidence level for one parameter of interest. The energy width of the lines is set to 0.01 keV.
