Abstract:
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 (647-685nm) data cube of the central
region (11'x11') of the Andromeda galaxy. The first application,
presented in this paper, is a radial-velocity catalogue (with
uncertainties of ∼2-6km/s) of nearly 800 emission-line point-like
sources, including ∼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.
Description:
We present a catalogue of the point-like sources in the central
11'x11' part of M31 obtained with SITELLE. For each source we report
the radial velocity as long as the spectrophotmetric flux of H-alpha,
[NII]6584 and the sum of the [SII]6717,6731 doublet. The ID of the
sources cross-matched with the catalogues from Merrett et al.
(2006MNRAS.369..120M 2006MNRAS.369..120M, J/MNRAS/369/120) and Halliday et al.
(2006MNRAS.369...97H 2006MNRAS.369...97H, J/MNRAS/369/97) are also indicated. We also
report the detection of the sources in the images of the Local Group
Galaxies Survey (Massey et al., 2006, 2006AJ....131.2478M 2006AJ....131.2478M).
