Notes.

⁽¹⁾

Measured brightness of the CC in the J- and K-band.

⁽²⁾

Spectral type of the CC as derived from the J − K colours.

⁽³⁾

Calculated brightness of the CC and brightness difference between primary in the V-band, assuming it is a companion.

⁽⁴⁾

Calculated brightness of the CC and brightness difference between primary in the V_UCAC (579−642 nm) band, assuming it is unrelated.
