abstract
SITELLE is an imaging Fourier Transform Spectrometer installed at the Canada-France-Hawaii Telescope since July 2015. It delivers spectral cubes covering an 11'x11' field-of-view with a seeing-limited spatial resolution and a tunable spectral resolution (R=1-10 000) in selected passbands of the visible band (350-900 nm). We present an accurate picture of the calibration accuracy of SITELLE's first data release. To this purpose, most of the operations of the reduction pipeline (ORBS) are described in details.

Mapping the Filamentary Nebula of NGC 1275 with Multiwavelength SITELLE Observations
Whole-nebula optical line maps of NGC 1275 show [O III] only in the core and a uniform, non-AGN hard ionizing source across the extended filaments.
