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 winds would be much stronger. ... In using what-if questions in the classroom, it is worth bearing in mind that students extrapolating the effects of new scenarios will encounter two different situations: direct changes to the new version of Earth and indirect changes resulting from the direct changes. ...

... Following a micrometeoritic impact in Rev.#961 (March 2005), a new hot column appeared, whose effects leak across the whole column RAWX=318 . While a correction for this hot column is possible and implemented for MOS1 exposures taken in Imaging Mode, the offset value in MOS1 exposures taken in Timing Mode is too high for any meaningful correction to be possible. ... mos1.evt is the name of the MOS1 event list . ...

... We have measured this "redshift" for the pink black holes, and allowed for it in our calculations. ... We see this effect in the emission from gas around these pink black holes, but it is far too small an effect to account for the pinkness. Thus the swirling motions of gas around or into the black holes cannot produc the colour. ... At first we thought that these things were normal blue black holes hidden behind clouds of interstellar dust, that absorbed the blue light and made them appear pink. ...
