Figure C.1

The five SDSS filters, showing the total transmission taking into account
atmospheric transmission and instrumental effects such as CCD efficiency.
Shown for reference is the spectrum (:math:`F_\lambda`) of a star
similar to Vega (alpha-Lyr), which for many years was used as a reference
flux for magnitude calibration.
