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) .

The night after the John Glenn program, I pitched the terraforming idea to my students. I asked them if they'd like to terraform Mars as a big class project; I wanted to throw the idea to them and see how they would react. Already I had a vision of splitting the class into several groups and having each group take charge of a portion of the project. ... Following my initial idea on how to conduct the project, I split the class into six groups, each student choosing his or her group. ...

Effect of chromospheric activity on the mean colours of late­type stars P. Amado and P.B. Byrne A&A, accepted July 96 In this paper we show, for the first time, the effect of activity on the (U \Gamma B) o vs. B \Gamma V ) o colour­colour diagram for a large sample of late type stars. we clearly see that for single­lined spectroscopic RS CVn systems there exists an ultraviolet excess over that recorded for quiescent stars of the same spectral type. ...

... In electron-positron colliders, effect of the lattice modification by opposing bunch focusing on the equilibrium radiation emittance is important at high values of the space charge parameter, so one should correctly evaluate this dynamic radiation emittance of the weak beam, which may differ a lot from the nominal emittance, already in the linear beam-beam force model. ... The linearized beam-beam force is equivalent to focusing insertion in linear lattice of the collider. ...
