FORS 1 - CCD System

Flat Field Images

Defects can been seen from these images. All images are 4 port readout. The flat fields were made with FORS 1 instruments and its filter set. These sky flat fields are pretty uniform, but within certain limits.

Sky flat field U_Bessel filter
( 360 nm, 50 nm bandwidth )
U-Band image cross section

Sky flat field B_Bessel filter
( 420 nm, 90 nm bandwidth )
B-Band image cross section

Sky flat field V_Bessel filter
( 520 nm, 100 nm bandwidth )
V-Band image cross section

Sky flat field R_Bessel filter
( 620 nm, 150 nm bandwidth )
R-Band image cross section

Sky flat field I_Bessel filter
( 800 nm, 120 nm bandwidth )
I-Band image cross section
