Notes. Column Δm provides the magnitude difference (mWAql − mcomp) as estimated from aperture photometry. Columns labelled V and Vcomp provide the visual magnitudes of W Aql as derived from the AAVSO (for 1993) or ASAS (for 2004) databases (Pojmanski 2002), and of its companion, respectively. The last column gives the measured separation δ.
