asinh MAGNITUDE SOFTENING PARAMETERS
|Band||b||Zero-Flux Magnitude [m(f/f0 = 0)]||m(f/f0 = 10b)|
|u||1.4 × 10-10||24.63||22.12|
|g||0.9 × 10-10||25.11||22.60|
|r||1.2 × 10-10||24.80||22.29|
|i||1.8 × 10-10||24.36||21.85|
|z||7.4 × 10-10||22.83||20.32|
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.
