Differential upper limits calculated from MAGIC observations.
| Energy | a.f. | Upper limit [10-12 erg cm-2 s-1] | ||
| [GeV] | 2011 Feb.–Apr. | 2011 Jun. | all 2011 data | |

| 147.1 | 0.63 | 10.7 | 16.0 | 10.9 |
| 303.6 | 0.16 | 0.8 | 2.9 | 0.8 |
Notes. Columns 1 and 2 give the energy and the respective absorption factor (a.f.) e−τ, where τ is the optical depth given by the EBL model of Domínguez et al. (2011). In Cols. 3–5, the observed differential upper limits for the individual periods and the overall data sample are shown.
