Abstract:
The Cosmic Dawn Survey (DAWN survey) provides multiwavelength
(UV/optical to mid-IR) data across the combined 59 deg2 of the
Euclid Deep and Auxiliary fields (EDFs and EAFs). In this work, the
first public data release from the DAWN survey is presented. The
catalogues made available herein consist of a subset of the full DAWN
survey that includes two EDFs: EDF North (EDF-N) and EDF Fornax
(EDF-F). Each field has been covered by the ongoing Hawaii Twenty
Square Degree Survey (H20), which includes imaging from the CFHT
MegaCam in the u filter and from the Subaru Hyper Suprime-Cam (HSC) in
the griz filters. Each field has been further covered by Spitzer/IRAC
3.6-4.5 micron imaging spanning 10deg2 and reaching ∼25mag AB
(5sigma). All present H20 imaging and all publicly available imaging
from the aforementioned facilities were combined with the deep
Spitzer/IRAC data to create source catalogues spanning a total area of
16.87deg2 in EDF-N and 2.85deg2 in EDF-F for this first release.
These catalogues are referred to as the "pre-launch" (PL), as Euclid
data is not yet public for these fields and therefore it is not
included. Photometry was measured from these multiwavelength data
using farmer, a novel and well validated model-based photometry code.
Photometric redshifts and stellar masses were computed using two
independent codes for modelling spectral energy distributions: EaZy
and LePhare. Photometric redshifts show good agreement with
spectroscopic redshifts (sigmaNMAD∼0.5eta<8% at i<25).
Number counts, photometric redshifts and stellar masses were further
validated in comparison to the COSMOS2020 catalogue. The DAWN survey
PL catalogues are designed to be of immediate use in these two EDFs
and will be continuously updated and made available as both new
ground-based data and spaced-based data from Euclid are acquired and
made public. Future data releases will provide catalogues of all EDFs
and EAFs and include Euclid data.
Description:
Tables from the paper, including exposure times, areas, depths, number
counts, and useful column names.
The DAWN survey DR1 catalogues are currently hosted in an online
repository accessible witth a username and password
(https://exchg.calet.org/dawn_edfn_edff_dr1/).
Please contact the authors of this work for access.
The DAWN survey DR1 catalogues will be available later at CDS.
