HyperLEDA documentation: parameter: ube

Effective (U-B) color

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

total asymptotic colors ubt for (U-B)T
total asymptotic colors bvt for (B-V)T
effective colors ube for ((U-B)e (colors within the effective aperture in which half the total B-flux is emitted)
effective colors bve for ((B-V)e (same as for ube)

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