Notes. λ is the central wavelength of the line given in air. EW is the equivalent width of the line measured on the outburst spectrum. A dash represents a non-detection of the line in the quiescent spectrum.
Measurements are strongly impacted by p-cyngi profiles in the line; as such, they are not considered when computing the final accretion rate.
ine is strongly blended with FeII at 1664 μm.
