TABLE 21
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.
