No evidence for TeV $\gamma$-ray emission from any compact or extended region associated with the remnant is seen and resulting upper limits at the 99.9% confidence level are up to a factor 10 lower than previously-published fluxes from CANGAROO. For SN1006 at its current epoch of evolution we define limits for a number of important global parameters. Upper limits on the $\gamma$-ray luminosity (for E = 0.26 to 10 TeV, distance d = 2 kpc) of $L_\gamma < 1.7$ $\times$ 1033 erg s-1, and the total energy in corresponding accelerated protons, $W_{\rm p}<1.6$ $\times$ 1050 erg are estimated (for proton energies $E_{\rm p} \sim 1.5$ to 60 TeV and assuming the lowest value n=0.05 cm-3 of the ambient target density discussed in literature). Extending this estimate to cover the range of proton energies observed in the cosmic ray spectrum up to the knee (we take here $E_{\rm p} \sim$ 1 GeV to 3 PeV, assuming a differential particle index -2) gives $W_{\rm p}<6.3$ $\times$ 1050 erg. A lower limit on the post-shock magnetic field of $B>25~\mu$G results when considering the synchrotron/inverse-Compton framework for the observed X-ray flux and $\gamma$-ray upper limits. %G English %Z HESS %L in2p3-00024436 %U https://in2p3.hal.science/in2p3-00024436 %~ IN2P3 %~ OBSPM %~ CEA %~ UNIV-PARIS7 %~ X %~ UPMC %~ LPTA %~ LLR %~ LPNHE %~ APC %~ CNRS %~ UNIV-MONTP2 %~ X-LLR %~ X-DEP %~ X-DEP-PHYS %~ DSM-IRFU %~ IRFU-APC %~ PSL %~ UPMC_POLE_2 %~ UNIV-MONTPELLIER %~ CEA-DRF %~ SORBONNE-UNIVERSITE %~ SU-SCIENCES %~ UNIV-PARIS %~ UP-SCIENCES %~ OBSPM-PSL %~ SU-TI %~ ALLIANCE-SU %~ UM1-UM2 %~ LPNHE-2
