Fig. A.1
Filter responses and TLS SITe CCD sensitivity curve. The transmissions of the TLS photometric system are shown as thick solid lines for the R-filter, I-filter, and the SITe 2k × 2k CCD detector sensitivity curve. The dashed lines are RI-filter profiles from the Cousins/Bessel system (Bessell 1979). The red cut-off of the TLS I-passband is imposed by the red fall-off of the SITe CCD detector.
