Estimates for the `u`, `g`, `r`, `i`, `z` colors of Vega and the Sun

Assuming `V`=+0.03 and `U`–`B` = `B`–`V` = `V`–`R`_{c} = `R`_{c}–`I`_{c} = 0.00, we find for the A0V star Vega the following:

g = -0.08 (±0.03) u-g = +1.02 (±0.08) g-r = -0.25 (±0.03) r-i = -0.23 (±0.02) i-z = -0.17 (±0.02)

where we used the Bilir, Karaali & Tunçel (2005) transformation for `g` and the Rodgers *et al.* (2006) transformations (plus the `u`′`g`′`r`′`i`′`z`′-to-`ugriz` transformations) for the `u`–`g`, `g`–`r`, `r`–`i`, and `i`–`z` colors. The error bars in parentheses are rough estimates of the systematic errors based upon the different values that different sets of transformation equations yield.

Assuming `M`(`V`)=+4.82, `U`–`B`=+0.195, `B`–`V`=+0.650, `V`–`R`_{c}=+0.36, and `R`_{c}–`I`_{c}=+0.32, we find for the Sun the following:

M(g)= +5.12 (±0.02) u-g = +1.43 (±0.05) g-r = +0.44 (±0.02) r-i = +0.11 (±0.02) i-z = +0.03 (±0.02)

where, again, we used the Bilir, Karaali & Tunçel (2005) transformation for `g` and the Rodgers *et al.* (2006) transformations (plus the `u`′`g`′`r`′`i`′`z`′-to-`ugriz` transformations) for the `u`–`g`, `g`–`r`, `r`–`i`, and `i`–`z` colors. As above, the error bars in parentheses are rough estimates of the systematic errors based upon the different values that different sets of transformation equations yield.
