  We present a detailed description of the wavelength, astrometric and
photometric calibration plan for SITELLE, the imaging Fourier transform
spectrometer attached to the Canada-France-Hawaii telescope, based on
observations of a red (647 - 685 nm) data cube of the central region (11$'
\times 11'$) of the Andromeda galaxy. The first application, presented in this
paper, is a radial-velocity catalogue (with uncertainties of $\sim 2 - 6$ km/s)
of nearly 800 emission-line point-like sources, including $\sim$ 450 new
discoveries. Most of the sources are likely planetary nebulae, although we also
detect five novae (having erupted in the first 8 months of 2016) and one new
supernova remnant candidate.
