TABLE 21
asinh MAGNITUDE SOFTENING PARAMETERS

BandbZero-Flux Magnitude [m(f/f0 = 0)]m(f/f0 = 10b)
u 1.4 × 10-1024.6322.12
g 0.9 × 10-1025.1122.60
r 1.2 × 10-1024.8022.29
i 1.8 × 10-1024.3621.85
z 7.4 × 10-1022.8320.32

     Note: These values of the softening parameter b are set to be approximately 1-sigma of the sky noise; thus, only low signal-to-noise ratio measurements are affected by the difference between asinh and Pogson magnitudes. The final column gives the asinh magnitude associated with an object for which f/f0 = 10b; the difference between Pogson and asinh magnitudes is less than 1% for objects brighter than this.
