Target Acquisition Reference Information . Table 7.3 on page 98 lists the effective areas of the four acquisition mirrors (in cm2) as a function of wavelength, to use to predict acquisition count rates. ... Also note that the proper use of this table requires compensation for the different energies of photons of different wavelengths, hence the last column, which is in picoergs per photon. ... Effective Areas of the Acquisition Mirrors . ... The effective areas shown are from Table 7.3 on page 98. ...

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) .
