Properties of DESI-LIS tomographic bins.

Redshift bin	N_obj	$\bar{n}$ $\bar n$ (gal pix⁻¹)	$\bar{n}$ $\bar n$ (gal str⁻¹)	Median z	x₀	σ	a
0 < z ≤ 0.3	14 363 105	2.652	2.655 × 10⁶	0.21	−0.0010	0.0122	1.257
0.3 < z ≤ 0.45	11 554 242	2.133	2.136 × 10⁶	0.38	0.0076	0.0151	1.104
0.45 < z ≤ 0.6	13 468 310	2.487	2.490 × 10⁶	0.51	−0.0024	0.0155	1.476

Notes. N_obj is the number of objects, $\bar{n}$ $\bar n$ is the mean number of objects, and median z is the median redshift of the tomographic bins. x₀, σ and a are the best fit values of parameters defining the modified Lorentzian fit to the photometric redshift error distribution p(z_s − z_p|z_p) (taken from H21).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
