Extinction Coefficients and Zero Points
The following are first order extinction coefficients based on obsevations obtained during the DECam Science Verification (Nov 1-19, 2012):
| Filter | Mean | sigma |
|---|---|---|
| u | 0.44 | 0.03 |
| g | 0.20 | 0.02 |
| r | 0.10 | 0.02 |
| i | 0.06 | 0.01 |
| z | 0.07 | 0.02 |
| Y | 0.07 | 0.01 |
