Abstract:
The Euclid mission will conduct an extragalactic survey over
15000deg2 of the extragalactic sky. The spectroscopic channel of the
Near-Infrared Spectrometer and Photometer (NISP) has a resolution of
R∼450 for its blue and red grisms that collectively cover the
0.93-1.89um range. NISP will obtain spectroscopic redshifts for
3x107 galaxies for the experiments on galaxy clustering, baryonic
acoustic oscillations, and redshift space distortion. The wavelength
calibration must be accurate within 5Å to avoid systematics in the
redshifts and downstream cosmological parameters. The NISP pre-flight
dispersion laws for the grisms were obtained on the ground using a
Fabry-Perot etalon. Launch vibrations, zero gravity conditions, and
thermal stabilisation may alter these dispersion laws, requiring an
in-flight recalibration. To this end, we use the emission lines in the
spectra of compact planetary nebulae (PNe), which were selected from a
PN data base. To ensure completeness of the PN sample, we developed a
novel technique to identify compact and strong line emitters in Gaia
spectroscopic data using the Gaia spectra shape coefficients. We
obtained VLT/X-SHOOTER spectra from 0.3 to 2.5um for 19 PNe in
excellent seeing conditions and a wide slit, mimicking Euclid's
slitless spectroscopy mode but with 10 times higher spectral
resolution. Additional observations of one northern PN were obtained
in the 0.80-1.90um range with the GMOS and GNIRS instruments at the
Gemini North observatory. The collected spectra were combined into an
atlas of heliocentric vacuum wavelengths with a joint statistical and
systematic accuracy of 0.1Å in the optical and 0.3Å in the
near-infrared. The wavelength atlas and the related 1D and 2D spectra
are made publicly available.
Description:
UV-NIR spectral atlas of PN which contain the following information
for identified emission lines:
(1) the ionic species within the limitations spelled out in the paper,
(2) the laboratory vacuum wavelengths,
(3) the observed heliocentric vacuum wavelengths,
(4) line fluxes integrated over the model Gaussian(s),
(5) a flag providing a goodness of fit estimate, and
(6) the line FWHM. The 1D and 2D data for each PN is also included in
FITS format and can also be access at
