TL;DR
MiniJPAS demonstrates the potential of a 1 deg^2 optical survey with 60 filters for highly accurate photometric redshifts, paving the way for large-scale cosmological studies like BAO measurements.
Contribution
This paper presents the methodology for obtaining and characterizing photometric redshifts in the miniJPAS survey, including improvements in accuracy assessment and error estimation techniques.
Findings
Photometric redshifts are highly accurate with the optimized method.
Odds parameter effectively predicts redshift outliers.
MiniJPAS achieves 17,500 galaxies/deg^2 with valid photo-z at r<23.
Abstract
MiniJPAS is a ~1 deg^2 imaging survey of the AEGIS field in 60 bands, performed to demonstrate the scientific potential of the upcoming JPAS survey. Full coverage of the 3800-9100 \AA range with 54 narrow and 6 broad optical filters allow for extremely accurate photo-z, which applied over 1000s of deg^2 will enable new applications of the photo-z technique such as measurement of baryonic acoustic oscillations. In this paper we describe the method used to obtain the photo-z included in the publicly available miniJPAS catalogue, and characterise the photo-z performance. We build 100 \AA resolution photo-spectra from the PSF-corrected forced-aperture photometry. Systematic offsets in the photometry are corrected by applying magnitude shifts obtained through iterative fitting with stellar population synthesis models. We compute photo-z with a customised version of LePhare, using a set of…
