Total (asymptotic) V-band magnitude

The V-band magnitudes are presently from the photometric measurements compilation (table a107) and from the B-V colour index from the colour catalogue (table a112) combined with bt.

Colors are given essentially in the UBV system. They are :

Total assymptotic colors bvtc and ubtc are corrected for galactic extinction, inclination and redshift effect (see e.g. btc documentation)
