The observations consist of three multispectral cubes covering an 11$^{\\prime}$ $\\times$11$^{\\prime}$ area allowing the investigation of both the spatial and spectral variation of 9 emission lines : [OII] $\\lambda\\lambda$3726+3729, [OIII] $\\lambda\\lambda$4959,5007, H$\\beta$, H$\\alpha$, [NII] $\\lambda\\lambda$6548,6583 and [SII] $\\lambda\\lambda$6716,6731.
